Single N-C Bond Becomes Shorter than a Formally Double N=C Bond in a Thiazete-1,1-dioxide Crystal: An Experimental and Theoretical Study of Strong Crystal Field Effects

3-Diethylamino-4-(4-methoxyphenyl)-1,1-dioxo-4H-1 lambda(6),2-thiazete-4-carbonitrile (DTC) is a synthetic compound that exhibits a significant similarity with)beta-sultamic drugs. Its core chemical moiety is an uncommon four-membered thiazete-1,1-dioxide heterocycle. Former crystallographic investigations carried out at room temperature on different DTC polymorphs and a chemically related compound showed a very unusual structural feature: within the conjugated -N-C=N-SO2- system, the formally single N-C bond is, on average, 0.018 angstrom shorter than the formally double N=C bond. In this work, the charge density distribution of DTC has been explored by both single-crystal X-ray diffraction at T = 100(2) K and quantum mechanical simulations, with the aim of gaining insights into the subtle interplay between structure, electron delocalization, and crystal field polarization effects. To this end, both local and nonlocal topological descriptors provided by the Quantum Theory of Atoms in Molecules have been employed. Topological and structural changes of crystalline and in vacuo DTC have been related to the smaller or larger importance of resonance forms in the -N-C=N-SO2- moiety. A rationale for the mentioned C-N/C=N bond length inversion is found in terms of the large DTC dipole moment enhancement occurring in the crystal, which stabilizes highly polar resonant forms that exploit more favorable electrostatic interactions with neighboring molecules. In turn, this causes a significant electronic rearrangement within the molecule that results in an unusual and counterintuitive bond length alternation pattern. Possible implications from the viewpoint of the accurate in silico modeling of crystal structures are discussed.

3,5-[5-Arylisoxazol-3-yl(4,5-dichloroisothiazol-3-yl)]-substituted 1,2,4-and 1,3,4-oxadiazoles: synthesis, palladium complexes, and catalysis of Suzuki reactions in aqueous media

A reaction sequence involving transformations of 5-(4-methylphenyl)isoxazole and 4,5-dichloroisothiazole derivatives containing an amidoxime group at position 3 allowed to synthesize the respective 3,5-isoxazolyl(isothiazolyl)-substituted 1,2,4-oxadiazoles. Selective recyclization of 4,5-dichloro-3-(1De-tetrazol-5-yl)isothiazole and 5-(4-methylphenyl)-3-(1De-tetrazol-5-yl)isoxazole gave 2,5-isoxazolyl-(isothiazolyl)-substituted 1,3,4-oxadiazoles. The obtained compounds combining three azole heterocycles in one molecule formed palladium complexes that showed high catalytic activity in Suzuki reactions in aqueous and aqueous alcohol media. The bimetallic reusable Pd/Fe catalyst obtained from palladium polyazole complex retained high catalytic activity after five uses.

Unusual oxidative dehydration of vic-[alkyl(aryl)thiol]-substituted aromatic (heteroaromatic) carboxamides

A new procedure was developed for the synthesis of nitriles of vic-[alkyl(aryl)sulfonyl] derivatives of benzoic, anthraquinonecarboxylic, and 4-isothiazolecarboxylic acids by the reactions of the corresponding vic-[alkyl(aryl)thio]-substituted aromatic (heteroaromatic) carboxamides with chlorine in organic solvents containing 20-65516 of water. Oxidative dehydration of 1-(butylthio)anthraquinone-2-carboxamide afforded 1-butyl-6,11-dihydro-3H-1lambda(4)-anthra[2,1-d]isothiazole-3,6,11-trione 1-oxide as a by-product.
