Isolation and characterization of salts of the organometallic synthon [Tp*W(NCMe)(CO)3] and its propionitrile analogue

Abstract

Trifluoromethanesulfonate and tetrafluoroborate salts of the previously in situ-generated synthetic precursor [Tp*W(NCMe)(CO)3] + and a propionitrile analogue, [Tp*W(NCEt)(CO) 3](CF3SO3), have been isolated and fully characterized. The complex cations exhibit a carbonyl-capped octahedral structure with Cs symmetry and undergo slow nitrile ligand exchange.
