Synthesis and characterization of novel inorganic/organometallic compounds

A novel optically active P-chirogenic ferrocene-fused benzophosphole, (S Fc ,R P )-4-phenylbenzo[b]ferroceno[d]phosphole, was synthesized by diastereoselective intramolecular cyclization of (S Fc )-1-(diphenylphosphanyl)-2-(2-lithiophenyl)ferrocene intermediates in two routes.The geometry of the new P-chirogenic ferrocenophosphole including absolute configuration of the phosphorous was disclosed by single crystal X-ray analysis of the palladium complex derived from the reaction of the phosphole with di-μ-dichloro-bis{2-[(dimethylamino)methyl]phenyl-C 1 ,N}dipalladium (II).
