Photoreduction of 2,2’-Bipyrimidine by Aliphatic Amines: Indirect Evidence of the Formation of a Very Short-Lived Ion Pair

As a part of a general investigation of the photoreactivity of the imine function n aza-aromatic molecules [1–3], we present here a discussion of the photoreduction f 2,2’-Bipyrimidine (22BPMY) by amines in acetonitrile as studied by nanosecond transient absorption and resonance Raman scattering.
