Sythesis of Heterocycles with Phosphorus - Arsenic and Arsenic - Arsenic Bonds: Reactions of Arsano-Substituted Cyano(triphenylphosphoranylidene)methanes with Dichloroaminophosphanes and -arsanes

The reaction of arsano-substituted cyano(triphenylphosphoranylidene)methane 2 with the dichloro(diisopropylamino)phosphane (3) in the presence of sodium tetraphenylborate yields the five-membered heterocycle 5 containing a phosphorus - arsenic bond. 5 isomerizes in solution within 3 days to give the 1,2-azaphosphetene derivative 7.An 1,2-azaarsetene 8 is obtained in the reaction of 2 with the dichloroaminoarsane 4.The five-membered heterocycle 6 is postulated as an intermediate.The X-ray analysis of 8 reveals a weak intramolecular contact (2.72 Angstroem) between a ring carbon atom and the exocyclic arsenic atom.This is responsible for an anchimeric acceleration of metathetical reaction of 7 and 8 with methyl iodide leading to the iodoarsanes 9 and 10.The mechanism of the formation of 7 and 8 is dicussed. - Keywords: Phosphorus - arsenic bonds, Arsenic - arsenic bonds
