On the reaction of benzohydroxamic acids with Lawesson's Reagent
Przychodzen,Chimiak
, p. 77 - 83 (1998)
Reaction of Lawesson's Reagent (LR) with two N-alkyl benzohydroxamic acids is presented. In addition to the desired thiohydroxamic acids 2, the reduction process provides amides 3 and thioamides 4. An unexpectedly pronounced solvent effect on the course o

An efficient protocol for synthesis of thioamides was developed via the microwave-Assisted iodine-catalyzed oxidative coupling of dibenzyl(difurfuryl)disulfides with amines. This process is scalable and tolerates a wide spectrum of amines to deliver the corresponding products in moderate to excellent yields in 10 minutes, providing a cheap and rapid approach to thioamides.

experimental part, p. 33 - 41 (2012/07/01)
Thioamides are prepared in moderate-to-good yields from the benzylamines or benzylamine derivatives by treatment with elemental sulfur under microwave and solvent-free conditions at 170.C in 15 min.
Lawesson's reagent for direct thionation of hydroxamic acids: Substituent effects on LR reactivity
Przychodzen, Witold
, p. 676 - 684 (2007/10/03)
To explore the generality and scope of direct thionation of hydroxamic acids (HAs), the reaction of various structurally diverse HAs with Lawesson's reagent was investigated. The yield of thiohydroxamic acid (THAs) is poor when HAs possess bulky acyl and/or N-substituents, acidic α-hydrogen atoms, or an N-phenyl ring. THAs yields were correlated with Brown sigma parameter. The relative rates of two subsequent processes kT2 and kR2 were also measured. Correlation was also found for methine proton chemical shifts of N-isopropyl benzothiohydroxamic acids.
Photochemical reactions of thiobenzamides bearing an allylic substituent on the nitrogen atom: Double-bond migration via tandem 1,4- And 1,6-hydrogen transfer
Aoyama, Hiromu
, p. 1851 - 1854 (2007/10/03)
N-(2-Phenylprop-2-enyl)thiobenzamides 1a-d underwent double-bond migration on irradiation to give N-(2-phenylprop-1-enyl)thiobenzamides 2a-d via consecutive 1,4- and 1,6-hydrogen transfer. Photoreaction of an N-(prop-2-enyl)thiobenzamide 1e and an N-(3-phenylprop-2-enyl)thiobenzamide if did not give migration products, but afforded pyrroles 3e and 3f and dealkylation products 4a in low yields.
Dicoordinated Phosphorus Compounds: a Novel 4,5-Disubstituted 1,2,3,4-Triazaphosphole. X-Ray Molecular Structures of a 2-N-BF3 Complex of 4,5-Diisopropyl-1,2,3,4-triazaphosphole and of its Tetramer. Conformation in the Crystalline Form and in Solution

The synthesis of the title compound is described.It may be stabilised by the reaction of its tetramer with BF3.The tetramer displays several isomers and conformers in solution; one of them has been isolated and its crystal structure determined.The crystal structure of the 2-N-BF3 complex of the parent 4,5-diisopropyl-1,2,3,4-triazaphosphole has also been obtained.
