[PPN][Fe₃(CO)₉(C⋮CH)] and [Fe₃(CO)₉(C⋮COTi(THF)₄Cl)] from the Reaction of Low-Valent Titanium with [Fe₃(CO)₉(CCO)]^2-

Abstract

TiCl 3 (DME) 1.5 (DME = 1,2-dimethoxyethane) and a Zn−Cu couple react with [PPN] 2 [Fe 3 (CO) 9 (CCO)] to give the new compound [PPN][Fe 3 (CO) 9 (C⋮CH)] ( I ) (70% yield), a known compound [Fe 3 (CO) 10 (CCH 2 )] ( II ) (9% yield), and another new compound [Fe 3 (CO) 9 (CCOTi(THF) 4 Cl)] ( III ). Compound I was characterized by 1 H and 13 C NMR, IR, mass spectrometry, and X-ray crystallography. Compound III was characterized by IR, mass spectrometry, 13 C NMR, and X-ray crystallography.
