Abstract

Abstract: Bismuth diphenylphosphanides Bi(NON R )(PPh2 ) (NON R =[O(SiMe2 NR)2 ], R= t Bu, 2, 6‐ i Pr2 C6 H3, Aryl) undergo facile decomposition via single‐electron processes to form reduced Bi and P species. The corresponding derivatives Bi(NON R )(PCy2 ) are stable. Reaction of the isolated Bi II radical . Bi(NON Ar ) with white phosphorus (P4 ) proceeds with the reversible and selective activation of a single P−P bond to afford the bimetallic μ, η 1:1 ‐bicyclo[1.1.0]tetraphosphabutane compound.
