Abstract

A model is discussed for the titanium species, [M], used in reductive couplings (McMurry Synthesis). Evidence is given for the presence of aluminium(0) in [M], generated in the TiCl3/LiAlH4 system. Reactions of this [M] with alcohols showinter alia titanium(III) signals with superimposed Al-splittings in the e.s.r. spectra, thus proving the existence of mixed Ti-Al complexes in the TiCl3/LiAlH4/ROH system.
