Pyridines bearing electron-donating substituents are useful catalysts for the rearrangement of O,S-dialkyl xanthates (1) to S,S-dialkyl dithiocarbonates (2). The rearrangement was analyzed by semiempirical and ab initio molecular orbital methods. The transition-structure analyses indicate that the pyridine-ring nitrogen of dialkylaminopyridine rather than the dialkylamino nitrogen attacks the O-alkyl carbon of xanthates. The reaction proceeds through an S(N)2 mechanism to give the dithiolcarbonate anion (RSCOS-) which acts as an actual catalyst.
