Several unusual P‐Se‐C and P‐Se‐C‐N heterocycles are formed by the reaction of [PhP(Se)( μ ‐Se)] 2 or (PhP) 3 Se 2 with alkynes or cyanamides, generated by the fragmentation of the organophosphorus–selenium compound and addition across the CC or CN triple bond of the organic substrate. X‐ray crystallographic analysis reveals an unexpected diversity of structural motifs within these heterocyclic systems, including P 2 SeCN, P 2 C 2 Se and PC 2 Se 2 rings.
