A method was developed for the production of dichloroketene acetals by the dehydrochlorination of chloral acetals in DMFA in the presence of triethylbenzylammonium chloride as phase-transfer catalyst.Sulfur monochloride, sulfur dichloride, and benzene sulfenyl chloride react with dichloroketene acetals with the formation of adducts (alkoxycarbonyldichloromethanesulfenyl chloride ClSCCl2COOR, alkoxycarbonyldichloromethanethiosulfenyl chloride ClSSCCl2COOR, and butyl phenylthiodichloroacetate C6H5SCCl2COOR respectively).The action of secondary amines on butoxycarbonyldichloromethanesulfenyl chloride gave sulfenamides R1R2NSCCl2COOBu.The reactions of butoxycarbonyldichloromethanethiosulfenyl chloride and butyl phenylthiodichloroacetate with secondary amines under various conditions led to degradation products.
