Abstract
The reaction of N, N-dibromobenzenesulfonamide (I) with cyclohexene (II) in formamide or dimethylformamide were studied. The reaction of I with II in formamide gave a major product, trans-2-bromo-1-cyclohexyl N-benzenesulfonylformimidate (III), and minor products, trans-1, 2-dibromocyclohexane (IV), trans-2-bromocyclohexyl formate (V), trans-2-bromocyclohexanol (VI) and benzenesulfonamide (VII).The reaction in dimethylformamide, contrary to that in formamide, gave another type of product, N, N-dimethyl-N'-benzenesulfonylformamidine (IX), IV, V and VI were also obtained as by-products.The mechanism to form these products was discussed.
