Syntheses and molecular structures of η3-[(η5-Cp*)(CO)2Fe–AsPC(SiMe3)2]M(CO)2(η5-Cp) (M = Mo, W): the first complexes featuring η3-arsaphosphaallyl ligands†
Abstract
Reaction of (η5-Cp)(CO)2MP
C(SiMe3)24a
(M = Mo) and 4b
(M = W) with (η5-Cp*)(CO)2Fe–As
C(NMe2)25 affords the η3-1-arsa-2-phosphaallyl complexes [(η5-Cp*)(CO)2Fe–AsPC(SiMe3)2]M(CO)2(η5-Cp)
6a and 6b, the molecular structures of which were determined by X-ray analyses.
