Bis(isopropoxy)titanium(IV)–propargyl complexes 146 and –allenyl complexes 147 are prepared by reaction of 1-substituted or 1,3-disubstituted prop-1-ynes with tert-butyllithium and followed by reaction with [Ti(OiPr)4] (Scheme 73).[281] The reactions of 146 or 147 with aldehydes give α-allenyl alcohols or threo-β-acetylenic alcohols, respectively, in high regioselectivities.
