Spectroscopic and Electrochemical Studies of Group 6 and 8 Transition Metal Carbonyl Derivatives of tris{(diphenylphosphinomethyl)dimethylsilyl}methane
Abstract:A new series of transition metal carbonyl complexes of tris{(diphenylphosphinomethyl)dimethylsilyl}methane are described in this work. Treatment of M(CO) 6 (M = Cr, W, Mo) and Fe 2 (CO) 9 with [(Ph 2 PCH 2 Me 2 Si) 3 CH] in tetrahydrofuran at elevated temperature resulted in the isolation of [M(CO) 3 {(Ph 2 PCH 2 Me 2 Si) 3 CH}] (M = Cr(1), Mo(2), W(3), Fe(4)) in good yield. These complexes have been characterized by elemental analysis, conductivity measurements, mass spectrometry, with IR, electronic, 1 H and… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
