Reactions of alkyl 1-chloroethyl carbonates 11 and 1-chloroethyl N, N-dialkyl carbamates 2 with MSCN (M= K, NH4) in acetone or in protic solvents (MeOH, HCONH2) afforded the corresponding thio-and/or isothiocyano derivatives in good yields. The origin of the N- bonded compounds is discussed and it is concluded that most of these compounds muse be due to a N condensation of the thiocyanate anion. During this work, we also found a new ...
