Synthèse et caractérisation de nouveaux complexes aryloxy à base de tungstène

Abstract

Disubstituted phenols react with the W(≡CC(CH3)3)(-CH2C(CH3 )3)3 tungsten carbyne complex, leading to the formation of new complexes where one, two or three neopentyl ligands have been replaced by aryloxy ones. Upon addition of four equivalents of phenol a W(=CHC(CH3)3)(-OAr)4 carbenic species is obtained. The structure of the complex with three 2,6-diphenylphenol aryloxy ligands is described.
