Synthesis and characterization of new aryloxy containing tungsten complexes

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tungsten carbyne complex, leading to the formation of new complexes where one, two or three neopentyl ligands have been replaced by aryloxy ones.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 obt...

Zusammenfassung: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tungsten carbyne complex, leading to the formation of new complexes where one, two or three neopentyl ligands have been replaced by aryloxy ones.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.
