MECHANISTIC STUDIES ON THE THIATION OF CARBONYLS BY LAWESSON'S REAGENT: THE ROLE OF A 3-COORDINATE PHOSPHORUS(V) SPECIES.

Structural, kinetic, and spectroscopic studies show that the mechanism for the thiation of organic carbonyls by Lawesson's reagent involves monomeric RPS2 intermediates.

Microwave assisted synthesis of ferrocenyl and hetaryl functionalized thioketones

The goal of the present study was elaboration of an efficient and simple protocol for the preparation of hetaryl and ferrocenyl functionalized thioketones via treatment of the corresponding ketones with Lawesson's reagent (L.R.) under microwave irradiatio

A novel application of 2-silylated 1,3-dithiolanes for the synthesis of aryl/hetaryl-substituted ethenes and dibenzofulvenes

Trimethylsilyldiazomethane (TMS-CHN2) reacts readily with hetaryl thioketones to give sterically crowded 2-trimethylsilyl- 4,4,5,5-tetrahetaryl-1,3-dithiolanes with complete regioselectivity at -75 °C as well as at rt. Thiofluorenone, a relatively stable and highly reactive aryl thioketone, yields upon treatment with TMS-CHN2at -60 °C the corresponding 1,3,4-thiadiazoline. This unstable cycloadduct undergoes decomposition at ca. -45 °C and the silylated thiocarbonyl S-methanide generated thereby is trapped with complete regioselectivity by aryl or hetaryl thioketones forming also sterically crowded 2-trimethylsilyl-1,3- dithiolanes. The obtained 1,3-dithiolanes, by treatment with an equimolar amount of TBAF in a one-pot procedure, are converted in high yields into hetaryl/aryl-substituted ethenes or dibenzofulvenes, respectively, via a cycloreversion reaction of the intermediate 1,3-dithiolane carbanion. The presented protocol offers a new, highly efficient approach to tetrasubstituted ethenes and dibenzofulvenes bearing aryl and/or hetaryl substituents.

Dichotomy of 1,3-dipolar cycloreversions in a tetrasubstituted 2,5-dihydro-1,3,4-thiadiazole

The cycloaddition of diphenyldiazomethane (8) to 16 thiohetones at 40°C which furnishes tetrasubstituted 2,5-dihydro-1,3,4-thiadiazoles, is followed by rapid N2 loss (see the preceding paper), with one exception: For the dihydrothiadiazole 10,

Regioselective reaction of fluorinated aryllithium reagents and carbon disulfide in cyclopentyl methyl ether: Efficient synthesis of dithioesters and liquid crystal compounds having a difluoromethyleneoxy moiety

Regioselective reaction (carbophilic over thiophilic attack) of several (o-fluorophenyl)lithium reagents with carbon disulfide was achieved to furnish dithioesters in good yields after alkylation, which are useful precursors of liquid crystal compounds having a difluoromethyleneoxy (-CF2O-) group. Running the reaction in the presence of a copper(I) salt catalyst and cyclopentyl methyl ether as a solvent is optimal.
