## Abstract A new method for the __in situ__ generation of various Ti(III) complexes is presented. Cyclohexadienyl‐Ti(IV) derivatives, which are readily prepared from the corresponding lithiated cyclohexadienes, afford the corresponding Ti(III) complexes upon thermal CTi‐bond homolysis. The Ti(III

In conventional metathetical reactions, product separation is based on solubility product differences, and the resulting products are often impure and require purification by recrystallization. A new approach to product separation is described that relies on the formation of an unstable, volatile by
