S,S'-Dialkyl N-(methyl)-, N-(phenyl)-, or N-(cyclopropyl)imidodithiocarbonates 5 were deprotonated by means of lithium diisopropylamide.The resulting α-thio-substituted lithium alkanides 6, which are stabilized by chelatization, were trapped as trimethylsilanes 7.Reaction of 6 with aldehydes or ketones yields the title compounds 20 via adducts 18 and loss of methanethiolate.
