The reaction of arylsulphonyl- or (phenylthio)-acetates 1 with carbon disulphide in a basic medium led to the corresponding ketene dithioacetals 2 in good yields.The o-chloro derivative 1d gave with carbon disulphide various products under different reaction conditions.However, the reaction of 1 with phenyl isothiocyanate primarily resulted in N-substituted pyrimidone derivatives 9, except for 1e which mainly gave S,N-analogues of dithioacetals 10e and 10f. β-Ketoesters 1g, h also reacted with phenyl isothiocyanate to afford 5-acyl-2-thioxo-4-pyrimidones 9g, h.The dependency of the polarisation of the double bond in ketene dithioacetals and their S,N-analogues on acceptor groups was investigated with the help of 13C NMR spectroscopy.
