Abstract

Abstract N-Cycloalkyl-N-halo-tosylamides 1a-c and 2a-b with three-, four-and five- membered cycloalkyl groups have been photolysed in methanol/dichloromethane at− 80 and− 10. The resultant ω-halo-alkylidenesulfonamides or N-cycloalkylsulfonamides are formed as outlined in Schemes 1 and 2. The influence of ring size on the tendency towards ring fission in intermediate amidyl radicals-resulting from N-Cl (N-Br) homolysis-is closely ...
