Phosphaalkene-substituted organo-group 15 compounds: synthesis and characterisation of (NHC)P–E t Bu 2 (E = P, As, Sb and Bi)

Herein, we present the synthesis and characterisation of new group 15 element compounds with low valent phosphorus atoms as substituents. This new series of compounds includes the heavier group 15 elements and represents the rare group of compounds with a direct P-E bond (E = P, As, Sb and Bi).
