The chromium Reformatsky reaction: Access to adjacent quarternary centers
α-Bromo ketones, -esters and -nitriles react with chromium dichloride and ketones in a Barbier-type reaction to yield the kinetic crossed aldol products with one or two new quarternary centers. The reaction does not require special activation of the reage

REFORMATSY TYPE REACTION BY MEANS OF Bu3SnAlEt2 or Bu3PbAlEt2
Treatment of α-halo carbonyl compounds with title Sn-Al or Pb-Al reagents provides enolates which react with aldehydes or ketones to give β-hydroxy carbonyl compounds effectively.
