Abstract
Abstract In situ deprotonation of 2-methyl, 2-chloromethyl-, 2-trimethylsilylmethyl-, and 2-methoxymethoxy-substituted allyl chlorides generates allyl carbenoids which insert into zirconacyclopentanes to afford allyl zirconocenes. Allyl bromides, p-toluenesulphonates, or N,N-diisopropylcarbamates may also be used. The allyl zirconocenes undergo further reaction with aldehydes / BF3.Et2O or ketones to give oxazirconacycles which may be protonated, halogenated, or oxygenated to afford organic products.
