Reactivity of Woollins’ Reagent toward 2-en-1-imines (Schiff bases) : a facile approach to synthesize new selenium-phosphorus-nitrogen heterocycles

Authors are grateful to the University of St Andrews for financial support and the EPSRC National Mass Spectrometry Service Centre (Swansea) for mass spectral measurements.Woollins’ Reagent serves as a reductive cycloaddition reagent, reacting with 2‐en‐1‐imines containing a conjugated C=C bond group (Schiff bases) leading to a series of four‐, five‐, six‐membered 1,2‐azaphospholidines incorporating one or two N‐P=Se linkages. Ten single crystal X‐ray structures confirming the formation of these small N‐P‐Se heterocycles are reported.PostprintPeer reviewe
