N-tosylarylimines also react with nucleophiles to give useful products. Phenacylimidates underwent [2 + 2]cycloadditions with diphenylketen; such reactions gave complex results with phenacylimines, but the latter reacted with conjugated dienes in the presence of BF3 to give [2 + 4]cycloaddition products in good yield.

water-soluble amide iridium complexes-catalyzed transfer hydrogenation reduction of N-sulfonylimine is developed, which can be carried out under environmentally friendly conditions, affording a series of sulfonamide compounds in excellent yields (96–98%). In comparison with organic solvents, water is shown to be critical for a high catalytic transfer hydrogenation reduction in which the catalyst loading can
The utility of N-sulfonylimines as radical acceptors was investigated under the different reaction conditions such as the stannyl radical-mediated addition reaction, the triethylborane-mediated tin-free radical reaction, and the zinc-mediated aqueous-medium radical reaction. The alkyl radical addition reaction of N-sulfonylimines proceeded effectively without the activation by Lewis acid. These reactions were successfully extended to one-pot reactions for preparing a wide range of amine derivatives. (C) 2008 Elsevier Ltd. All rights reserved.
