The preparation of three N-substituted-N-2-phenylethenylsulphonamides is described.On reduction with magnesium and methanol N-phenyl-N-2-phenylethenyltoluene-p-sulphonamide gives cleanly N-phenyl-N-2-phenylethylamine, N-phenyl-N-2-phenylethenylmethanesulphonamide gives some N-phenyl-N-2-phenylethylamine, but also N-phenyl-N-2-phenylethylmethanesulphonamide and N-phenylmethanesulphonamide, and N-cyclohexyl-N-2-phenylethenylmethanesulphonamide gives N-cyclohexyl-N-2-phenylethylmethanesulphonamide and N-cyclohexylmethanesulphonamide.The nitrogen-sulphur bond in N-methyl-N-phenyltoluene-p-sulphonamide and in N-toluene-p-sulphonylpiperidine is also reductively cleaved by magnesium and methanol, but not that in N-methyl-N-phenylmethanesulphonamide.
