Versatility of titanium: Titanocene(III) complexes catalyze Barbier‐type allylations, intramolecular crotylations (cyclizations), and prenylations of a wide range of aldehydes and ketones. These reactions take place at RT under mild conditions compatible with many functional groups; provide good yields of open‐chain and cyclic homoallylic alcohols, including heterocyclic derivatives; and can be conducted
钛的通用性:钛茂(III)配合物催化Barbier型烯丙基化,分子内crotylations(环化)和各种醛和酮的异戊烯基化。这些反应在室温下与许多官能团相容的温和条件下进行。提供高收率的开链和环状均丙醇,包括杂环衍生物;并且可以通过使用对映体纯的钛催化剂来对映选择性地进行。
