The reaction of methyl (bismethyl thio) sulphonium hexachloro-antimonate 1 with N-(2-allylphenyl)benzamide 2 gives the 4-methylthiomethyl-4,5-dihydro-3,1-benzoxazepine 4. Other electrophilic reagents reacts with 2 to give exclusively or preferentially products of addition to the allylic double bond.
