✦ Synopsis

Abstract

Solutions of the title compounds are accessible from organolithium reagents and trialkoxyzirconium chloride (equation 2). In contrast to their titanium analogues, vinylzirconium reagents are stable enough to be employed. Generally, organozirconium reagents are highly selective aldehyde and ketone carbonylophiles of exceedingly low basicity (Tables 1, 2, 3 and typical procedure).

## 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.
