Tandem insertion of allenyl carbenoids and aldehydes into zirconacycles: an unexpected cyclisation

Abstract

Allenyl carbenoids (3-chloro-1-lithioalk-1-ynes) insert into zirconacyclopentanes and zirconacyclopentenes to afford cyclic η 3 -allenyl/prop-2-ynyl zirconocene complexes which give allenyl, alkynyl or cyclised-alcohol products on addition of aldehydes activated with boron trifluoride–diethyl ether.
