EtOH at room temperature gave cis-Ni(II)-3-alkylimino-3-alkylthio-1-arylpropenethiolates 3 in excellent yields. Heating a mixture of 3 and alkyl- or arylthiols in 1,2-dichloroethane gave new keteneS,N-acetals 4 having new alkyl- or arylthio groups depending on the thiols employed. For the first time, 5-aryl-3-(arylthio)isothiazoles were prepared from 2 with an arylthio group according to a known procedure
