A highly efficient three-component coupling reaction between thioformamides and organolithium and Grignard reagents was developed. The generality of the process has been demonstrated by using various combinations of reactants and reagents. Information about the mechanism of the reaction has come from 1H and 13C NMR spectroscopic detection of the key intermediate. The LiS group in the intermediates generated by addition of the organolithium reagents to the thioformamides serves as a leaving group. The solid byproduct formed in these reactions, formulated as [LiSMgBr], can be used as a thiolating agent to transform acid chlorides into thioic acids and thioic acid anhydrides. Copyright

2-Aminomethylpyridines were synthesized from α-aminonitriles containing various substitutents at the α-carbon atom and acetylene at elevated pressures and temperatures in the presence of η5-dicyclopentadienylcobalt (cobaltocene) as catalyst.The
