Selectivities in the Reactions of Alkyl‐, Aryl‐ and Heterosubstituted Organotitanium Compounds Preliminary Communication

Abstract

Abstract Solutions of the title compounds R‐Ti(OR′) 3 ( 1 ) are generally available from organolithium (or magnesium) derivatives according to equation 1. It is shown ( Table 1 ) that some heterosubstituted organotitanium compounds are more stable thermally than their lithium counterparts. The reagents 1 are highly selective carbonylophiles ( Tables 1 and 2 ), their reactivity can be modified by variation of the R′O‐group ( Table 3 ) and with the chiral ( S )‐2‐methyl‐l‐butoxy group an enantioselective addition can be achieved [equ. 2].
