Stereochemical evidence for a carbonium ion rearrangement during reaction of dimethyltitanium dichloride with a ketone
Abstract
Racemization during the reaction of dimethyltitanium dichloride with the 2,2-disubstituted cyclopentanone (–)-(3) of high enantiomeric purity provides stereochemical evidence for a carbonium ion rearrangement during this dimethylation process.
