Conclusions
-
1.
Sulfonium dinitroylides\(R_2 \mathop S\limits^ + - C(NO_2 )_2^ - \) are cleaved at the\(S - C_{NO_2 } \) bond by electrophiles such as halogens (chlorine, bromine, bromine chloride), sulfuryl chloride, hydrogen halides (chloride and bromide), giving the corresponding di- or monohalodinitromethanes.
-
2.
Phenylsulfenyl chloride reacts with\((CH_3 )_2 \mathop S\limits^ + - C(NO_2 )_2^ - \), forming dinitrobis(phenylthio)methane and dtnitrophenylthiomethane.
-
3.
Compounds containing a positive halogen (N-haloamides, N-chloroalkylnitramines, BrONO2, SO2FCl, CH3CO2C1) react with\((CH_3 )_2 \mathop S\limits^ + - C(NO_2 )_2^ - \) to give the corresponding dihalodinitromethanes.
-
4.
Electrophiles (chlorine, bromine, phenylsulfenyl chloride) are capable of cleaving the\(S - C_{NO_2 } \) bond of dinitromethylsulfonium salts, forming the corresponding monosubstituted dinitromethane, ClCH(NO2)2, BrCH(NO2)2, and PhSCH(NO2)2. On the basis of our results we propose a scheme for the reaction of\((CH_3 )_2 \mathop S\limits^ + - C(NO_2 )_2^ - \) with phenylsulfenyl chloride and compounds containing a positive halogen.
