Phosphorylation of alcohols is a fundamentally important reaction in both life science and physical science. Product phosphate monoesters play key roles in living organisms, natural products, pharmaceuticals, and organic materials. Most of the chemical methods to date for synthesizing phosphate monoesters, however, require multistep sequences or are limited to specific types of substrates possibly due to harsh conditions. An alternative way to enable the simple production of phosphate monoesters from highly functionalized precursor alcohols is, thus, highly desired. We report herein a catalytic phosphorylation of alcohols with high functional group tolerance using tetrabutylammonium hydrogen sulfate (TBAHS) and phosphoenolpyruvic acid monopotassium salt (PEP-K) as the catalyst and phosphoryl donor, respectively. This method enables the direct introduction of a nonprotected phosphate group to the hydroxy group of a diverse menu of alcohol substrates, including functionalized small molecules, carbohydrates, and unprotected peptides. Nuclear magnetic resonance, mass spectrometric, and density functional theory analyses suggest that an unprecedented mixed anhydride species, generated from PEP-K and TBAHS, acts as an active phosphoryl donor in this reaction. This operationally simple and chemoselective catalytic phosphorylation allows for the efficient production of densely functionalized O-phosphorylated compounds, which are useful in diverse fields including biology and medicine.

Experimental solubilities have been determined by spectrophotometric methods for 1-chloro-4-bromobenzene, 1,4-dibromobenzene, 1,4-dichloro-2-nitrobenzene, benzoic acid, 4-nitrobenzoic acid, 3,5-dinitrobenzoic acid, 2-methoxybenzoic acid, 4-methoxybenzoic acid, 3-chlorobenzoic acid, 3,5-dinitro-2-methylbenzoic acid, 2-methylbenzoic acid, 3-methylbenzoic acid, 3,4-dichlorobenzoic acid, benzoin, 4-tert-butylbenzoic acid, 4-chlorobenzoic acid, 3,4-dimethoxybenzoic acid, 3,4,5-trimethoxybenzoic acid and o-acetoacetaniside dissolved in 2-ethyl-1-hexanol at 298.15 K. Our experimental measurements, combined with published solubility data retrieved from the published chemical and engineering literature, were used to derive Abraham model correlations for solute transfer into 2-ethyl-1-hexanol from both water and from the gas phase. The derived Abraham model correlations were found to back-calculate the measured experimental values to within +/- 0.12 log units (or less).

The controllable phosphorylations of thioesters were developed. When the reaction was catalyzed by a palladium catalyst, aryl or alkenyl phosphoryl compounds were generated through decarbonylative coupling, while the benzyl phosphoryl compounds were produced through deoxygenative coupling when the reaction was carried out in the presence of only a base.

Microplastics (MPs) and nanoplastics (NPs) are ubiquitous and contaminate soil, surface waters, atmospheric aerosol, precipitations, indoor and outdoor environments. However, the occurrence, transformation and fate of NPs in the environment are still unclear. In this work, polystyrene nanoparticles (PS-NPs) are used as a proxy of NPs to study their reactivity and potential impact on atmospheric and surface waters. In particular, the reactivity with hydroxyl radicals (center dot OH) in the aqueous phase is investigated. For the first time, a reactivity constant for the reaction of NPs with center dot OH is measured, strongly dependent on the exposed partide surface area of NPs. Degradation products (short chain carboxylic acids and aromatic compounds), obtained by direct and center dot OH-mediated photolysis of PS-NPs suspensions, are identified by mass spectrometry. Irradiation of a PS-NPs suspension under natural sunlight for 1 year has shown the formation of formic acid and organic compounds similar to those found in riverine and cloud dissolved organic matter, which could contribute significantly to the dissolved organic matter in the aqueous phase.

The palladium-catalyzed cross-dehydrogenative coupling (CDC) followed by an intramolecular cyclization between arylquinazolinones and aldehydes has been described. This viable transformation provides a variety of novel substituted hydroxyisoindolo[1,2-b]quinazolinone compounds in moderate to good yields. Additionally, the reaction is performed with toluene in place of benzaldehyde by using an excess amount of tert-butyl hydroperoxide (TBHP) as the oxidant in good yield.

We report the preparation of lithium-salt-free KDA (potassium diisopropylamide; 0.6 m in hexane) complexed with TMEDA (N,N,N ‘,N ‘-tetramethylethylenediamine) and its use for the flow-metalation of (hetero)arenes between -78 degrees C and 25 degrees C with reaction times between 0.2 s and 24 s and a combined flow rate of 10 mL min(-1) using a commercial flow setup. The resulting potassium organometallics react instantaneously with various electrophiles, such as ketones, aldehydes, alkyl and allylic halides, disulfides, Weinreb amides, and Me3SiCl, affording functionalized (hetero)arenes in high yields. This flow procedure is successfully extended to the lateral metalation of methyl-substituted arenes and heteroaromatics, resulting in the formation of various benzylic potassium organometallics. A metalation scale-up was possible without further optimization.

Herein, we have introduced sulfonimidoyl azide as a precursor in a Cu-catalyzed Chan-Evans-Lam reaction with aryl boronic acid for the synthesis of N-aryl sulfonimidamide. The CuCl catalyzed reactions of sulfonimidoyl azides and aryl boronic acids have been proceeded in the presence of triethylamine (Et3N) as base in methanol at room temperature under oxygen atmosphere and resulted moderate to good yields of corresponding products in very short time. The synthetic utilities of N-aryl sulfonimidamides have been established by iodination reactions and Suzuki-Miyaura coupling reactions.

An efficient strategy for the synthesis of all carbon quaternary centres has been developed via Bronsted acid-promoted highly regioselective intermolecular Friedel-Crafts reactions of heteroarenes or arenes with spiro-epoxyoxindoles. In addition, we have successfully performed the ring opening reaction in relatively cheap condition using water as a solvent. Beneficially, we have utilized the methodology as the key step for the synthesis of advanced precursors of various natural and unnatural indole alkaloids.

A method for the annulation of amines and carboxylic acids to form pharmaceutically relevant azaheterocycles via organophosphorus P-III/P-V redox catalysis is reported. The method employs a phosphetane catalyst together with a mild bromenium oxidant and terminal hydrosilane reductant to drive successive C-N and C-C bond-forming dehydration events via the serial action of a catalytic bromophosphonium intermediate. These results demonstrate the capacity of P-III/P-V redox catalysis to enable iterative redox-neutral transformations in complement to the common reductive driving force of the P-III/P-V couple.
