An efficient isocyanide-based synthesis of S-thiocarbamates was discovered and thoroughly investigated. The new reaction protocol is a one-pot procedure allows the direct conversion N-formamides into thiocarbamates by initial dehydration with p-toluene sulfonyl chloride to respective isocyanide subsequent addition sulfoxide component. Contrary recent literature, which also uses isocyanides as s...

The bond dissociation enthalpies (BDEs) of sulfur and selenium ylides have been estimated by applying MP2/6-311++G(3df,2p)//MP2/6-31G(d,p), G3, and other computational methods. Computed sulfoxide bond enthalpies were compared to experimental results to ensure the reliability of the computational methods before extending to related compounds. The examined ylides include the following: sulfoxides...
