| Abstract: | 3,4,5-Triphenyl-1-(+)-neomenthyl-1,2-diphosphole and 3,5-di-( tert -butyl)-1-(+)-neomenthyl-1,2,4-triphosphole were obtained by alkylation of sodium 3,4,5-triphenyl-1,2-diphosphacyclopentadienide and 3,5-di-( tert -butyl)-1,2,4-triphosphacyclopentadienide with (−)-menthyl tosylate in 70% yield. These P -heterocycles react with [W(CO) 5 (THF)] to give the 1:1 complexes with high regioselectivity - tungsten is coordinated exclusively by the dicoordinated phosphorus atom P 2 . Complex formation causes quite pronounced charge redistribution within the heterocyclic moieties and has also a rather pronounced impact on the frontier molecular orbitals of the ligands. This is reflected in a strong bathochromic shift of the lowest-energy absorption band and in a change of the corresponding electronic transition from a π-π* transition for the ligands to a metal-to-ligand charge transfer transition (MLCT) for the tungsten complexes.
