theoretical analysis based on the group electrophilicity index, a reactivity descriptor that may be taken as a measure of the ability of a group or fragment to depart from a molecule with the bonding electron pair. The theoretical analysis is in accordance with the experimental results obtained and predicts relative nucleofugalities of O-aryl vs. S-aryl groups in a series of diaryl thiocarbonates not experimentally

Cu(OAc)(2)-promoted TBHP oxidative coupling reaction of formamides with thiols successfully proceeded through direct C-H bond activation of formamides. The corresponding S-phenyl dialkyl thiocarbamate compounds were formed with high yield under solvent-free conditions.

Various thiocarbonyl compounds such as thioamides, thiocabamate, thiocarbonate, trithiocarbonate, and thioketone were readily reacted with t-butyl thionitrate (t-BuSNO2) to give the corresponding carbonyl compounds in excellent yields under mild conditions. Desulfurization seems to be initiated the selective nitrosation on the sulfur atom of thiocarbonyl group with t-BuSNO2.
