Abstract

Several unusual P-Se-C and P-Se-C-N heterocycles are formed by the reaction of [PhP(Se) (mu-Se)](2) or (PhP)(3)Se-2 with alkynes or cyanamides, generated by the fragmentation of the organophosphorus-selenium compound and addition across the Cequivalent toC or Cequivalent toN triple bond of the organic substrate. X-ray crystallographic analysis reveals an unexpected diversity of structural motifs within these heterocyclic systems, including P2SeCN, P2C2Se and PC2Se2 rings.
