Reactions of [Ru3(CO)12] with thiosaccharin: Synthesis and structure of di-, tri-, tetra- and penta-ruthenium complexes containing a thiosaccharinate ligand(s)

Reactions of [Ru3(CO)12] with thiosaccharin (tsacH) at different temperatures have been investigated. At 40 C, the diruthenium complex [Ru2(CO)6(mu-N,S-tsac)2] (1) is produced and whose ruthenium atoms are bridged by two tsac ligands that are oriented in a head-to-tail fashion. When this reaction is carried out at 66 C, the tri-, tetra- and penta-ruthenium complexes [H2Ru3(CO)7(mu-N,S-tsac)(mu-C,N?C6H4CNSO2)(mu3-S)] (2), [Ru4(CO)12(mu-N,S-tsac)2(mu4-S)] (3) and [H2Ru5(CO)13(mu-N,S-tsac)(mu-C,N?C6H4CNSO2)(mu3-S)(mu4-S)] (4), respectively, are also isolated in addition to 1. The triruthenium complex 2 exhibits an arachno SRu3 polyhedron containing edge-bridging tsac and C6H4CNSO2 ligands. The tetraruthenium complex 3 consists of two [Ru2(CO)6(mu-N,S-tsac)] fragments linked via a mu4-S ligand, while the pentaruthenium complex 4 is composed of individual Ru3 and Ru2 units linked via a mu4-S ligand. At 81 C, the same reaction furnishes the pentaruthenium complex [HRu5(CO)15(mu-N,S-tsac)(mu5-S)] (5) containing tsac and mu5-S bridging ligands. The molecular structures of the new complexes have been determined by single-crystal X-ray diffraction analyses, and the bonding in each product has been examined by DFT.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C7H5NO2S2, you can also check out more blogs about27148-03-4

SPME/GC-MS characterization of volatile compounds of Chinese traditional-chopped pepper during fermentation

Fermented-chopped pepper is a traditional-fermented vegetable in China. Chopped pepper is generally made with pepper, garlic, and ginger. In present study, the volatile compounds, obtained from chopped peppers during spontaneous fermentation, were analyzed by solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS). One hundred and forty volatile compounds were identified by solvent-assisted flavor evaporation, including 42 hydrocarbons, 34 esters, 16 alcohols, 21 aldehydes, 8 acids, 4 ketones, 4 ethers, and 9 other compounds. Alcohols, esters, and ketones were the dominant volatile fractions. The terpenes were found to be the main contributors to chopped pepper samples. It is important to note that among terpenes, such as beta-phellandrene, alpha-curcumene, elemene, geraniol and nerolidol may originated from ginger. In addition, diallyl disulfide and diallyl sulfide, the two major sulfur components, may originated from garlic volatile oils. The results indicated that the ginger and garlic as raw materials played an important role in the flavor of chopped pepper. The contents of esters significantly increased during the fermentation process, the ethyl palmitate and ethyl linoleate were the main esters. The content of beta-ionone as an degradation compound of carotenoids increased significantly with the fermentation period. Principal component analysis (PCA) was applied to discriminate the fermented-chopped peppers samples according to different times, and the fermented-chopped pepper samples were clearly differentiated on PCA plots. The fermentation stage was mainly affected by esters, alcohols, aldehydes and terpenes.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 272-16-2, help many people in the next few years.Safety of Benzo[d]isothiazole

Meta-analysis of the core aroma components of grape and wine aroma

Wine aroma strongly influences wine quality, yet its composition and its evolution during the winemaking process are poorly understood. Volatile compounds that constitute wine aroma are traditionally divided into three classes according to their origin: grape, fermentation, and maturation aroma. We challenge this view with meta-analysis and review of grape and wine volatiles and their precursors from 82 profiling experiments. We compiled a list of 141 common grape and wine volatiles and quantitatively compared 43 of them. Our work offers insight into complex relationships between biosynthesis of aroma in grapes and the changes during the winemaking process. Monoterpenes are one of the largest and most researched wine aroma compounds. We show that their diversity in wines is mainly due to the oxidative metabolism of linalool in grapes. Furthermore, we demonstrate that most of the linalool produced in grapes is converted to these oxidized derivatives.

Opioid Receptor Modulators with a Cinnamyl Group

To obtain selective and potent opioid receptor ligands, we synthesized dehydro derivatives of alvimopan and found compound (28f), a selective but modest affinity MOR antagonist weaker than alvimopan (1). We replaced the arylpiperidine unit by an arylpiperazine to obtain the 1-(alpha-carboxycinnamyl)-4-arylpiperazines like 13h, which to our surprise had no MOR or DOR activity but was a KOR agonist with moderate affinity. In contrast, literature examples of arylpiperazines 4 and 5 were reported to be pan opioid receptor antagonists, while 6 was a MOR agonist. Two compounds (13l and 11b) showed analgesic response in tail flick test which was blocked by pretreatment with norbinaltorphimine (norBNI). Among 10 1-(alpha-carboxycinnamyl)-4-arylpiperidines, compound 28g and five others were specific MOR antagonists. Interestingly, compound 26b of this series was found to be more potent than naloxone but weaker than 1. Docking studies have explained differential activities of the above piperazines and piperidines.

Anthropogenic contributions to global carbonyl sulfide, carbon disulfide and organosulfides fluxes

Previous studies of the global sulfur cycle have focused almost exclusively on oxidized species and just a few sulfides. This focus is expanded here to include a wider range of reduced sulfur compounds. Inorganic sulfides tend to be bound into sediments, and sulfates are present both in sediments and the oceans. Sulfur can adopt polymeric forms that include [Formula presented] bonds. This review examines the global anthropogenic sources of reduced sulfur, updating emission inventories and widening the consideration of industrial sources. It estimates the anthropogenic fluxes of key sulfides to the atmosphere (units?Gg?S?a??1) as: carbonyl sulfide (total 591: mainly from pulp and pigment 171, atmospheric oxidation of carbon disulfide 162, biofuel and coal combustion, 133, natural 898?Gg?S?a??1), carbon disulfide (total 746: rayon 395, pigment 205, pulp 78, natural 330?Gg?S?a??1), methanethiol (total 2119: pulp 1680, manure 330, rayon and wastewater 102, natural 6473?Gg?S?a??1), dimethyl sulfide (total 2197: pulp 1462, manure 660 and rayon 36, natural 31,657?Gg?S a??1), dimethyl disulfide (total 1103: manure 660, pulp 273, natural 1081?Gg?S?a??1). The study compares the magnitude of the natural sources: marine, vegetation and soils, volcanoes and rain water with the key anthropogenic sources: paper industry, rayon-cellulose manufacture, agriculture and pigment production. Industrial sources could be reduced by better pollution control, so their contribution may lessen over time. Anthropogenic emissions dominate the global budget of carbon disulfide, and some aromatic compounds such as thiophene, with emissions of methanethiol and dimethyl disulfide also relatively important. Furthermore, industries related to coal and bitumen are key sources of multi-ringed thiophenes, while food production and various wastes may account for the release of significant amounts of dimethyl disulfide and dimethyl trisulfide.
