Abstract
The existence of the proposed benzylidene intermediate 11 in the Petasis be nzylidenation procedure is supported by the isolation of cyclometallated pr oduct 8. A model is proposed which explains the empirical observation that a large acid residue and a small ester group are needed for good stereosele ctivity in benzylidenation reactions.
