Complexes of 2-chloroethoxybis(trifluoromethyl)phosphine with carbonyls of manganese, iron, and cobalt
Abstract
The compound P(CF3)2(OCH2CH2Cl), L, can be prepared in high yield by the reaction of P(CF3)2Cl with 2-chloroethanol. The ligand displaces CO or PF3 from [Co(CO)3(NO)], [CoH(PF3)4], and [MnH(CO)5], but [{Fe-(η-C5H5)(CO)2}2] gives a little [Fe(η-C5H5)(CO)2{P(CF3)2}] as the only isolable organometallic product. Treatment of [MnH(CO)4L] with CCl4 gives a mixture of [MnCl(CO)4L] and [Mn2Cl2(CO)8]. The complex cis-[Mn(CO)4(η-C2H4)2O}] is formed by a novel rearrangement in the reaction of [MnH(CO)4L] with NMe3 or of [MnCl(CO)4L] with sodium amalgam.
