Method of lithiating a tertiary chloro alkyl compound and the product provided by said method

Abstract

A method of treating a hydrocarbon containing a tertiary chloroalkyl groups to convert it to an allylic lithium by dehydrochlorinating the above either simultaneously or sequentially, to first dehydrochlorinate the compound to form a terminal unsaturation and then converting it to an allylic lithium derivative. Alkyl lithium is used to generate the allylic lithium derivative alone or with a complexing agent. The complexing agents are ethers, such as tetrahydrofuran, diamines with diethyldiamino ethane being a preferred one, and t-buOK. The solvents used are tetrahydrofuran, the cycloalkanes such a cyclohexane and the alkanes such as hexanes, pentanes and heptanes.
