Bismuth diphenylphosphanides Bi(NON R )(PPh 2 ) (NON R =[O(SiMe 2 NR) 2 ], R= t Bu, 2,6‐ i Pr 2 C 6 H 3 , Aryl) undergo facile decomposition via single‐electron processes to form reduced Bi and P species. The corresponding derivatives Bi(NON R )(PCy 2 ) are stable. Reaction of the isolated Bi II radical . Bi(NON Ar ) with white phosphorus (P 4 ) 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.
