Metallocarbonyl compounds

TMS-Cl or TMS-I, formed in situ, worics as the promoter in addition reactions of zinc homoenolates ((3-metallocarbonyl compounds), generated from 1-alkoxy-l-siloxycyclopropanes and ZnXz (equation 7). No reaction t es place with the purified zinc homoenolates. In contrast, titanium homoenolates are reactive enough to add to aldehydes in the absence of the Lewis acid promoter.Related reactions of zinc esters with aldehydes in the presence of (lVO)3TiCl have been reported (equation 8). ... [Pg.327]
