Radical reactions of N-haloamides with olefins. XIII. Quantum yields for the photochemical addition of N-halo-N-hydroamides and N-chlorosuccinimide to 3,3-dimethyl-1-butene

Abstract

The quantum yield of the photochemically initiated radical chain addition of ZCONHX to 3,3-dimethyl-1-butene increases with Z in the order CH3 < ClCH2 < C2H5O < CCl3 < CF3 and is governed by the transfer step. The quantum yields are similar for N-chloroacetamide and N-chlorosuccinimide but the yield of addition is lower with the latter due to photodecomposition of the 1,2-adduct.
