Toluene Wolff rearrangement

RJi (II) catalyzed conversion of 2-diazo-jd-ketophosphonates 166 via a Wolff rearrangement in toluene under reflux was suggested to give ketenes 167, which simultaneously via the intramolecular nucleophilic attack of the ether-oxygen followed by migration of the silyl group to afibrd the ketene... [Pg.220]

The diazo ketone 97 upon refluxing in toluene in the presence of Rh(II) catalyst underwent Wolff rearrangement to give E/Z mixture of ester 98. The ester 98 results from the attack by the oxygen atom of the methoxy or the benzyloxy group on the ketene resulting from the Wolff rearrangement and p-elimination. ... [Pg.269]
