Photoreactions of α,β-unsaturated γ,δ-epoxy nitriles with amines. The novel photoadditions of tertiary amines to the α-position of the nitriles
Abstract
Direct irradiation of α,β-unsaturated γ,δ-epoxy nitriles (e.g.1) and tertiary amines gives rise to a novel 1:1 α-addition and subsequent retro-Michael reaction leading to α-alkylidenenitriles (e.g.2).
