method for the preparation of W(CO)3(PR3)3 and (CO3(η6-arene) complexes. The reactions W(CO)3(L)3 [L = PMe3, PEt3, PMe2Ph, PMePh2, PhP(CH2Ch2PPh2)2, and CH3C(Ch2PPh2)3]with CF3SO3H in CH2Cl2 solution yield the hydrido derivaties W (H)(CO)3(L)+3 which were characterized by their 1H and 31 P NMR spectra at different temperatures. These studies show the W(H)(CO)3(L)+3 complexes to be fluxional as a result
