While the 1,2-addition of Grignard reagents to ketones is undoubtedly a powerful transformation, oftentimes selectivity issues arising from competitive alpha-deprotonation detract from the use of these reagents.
Sigma-Aldrich.com presents an article concerning New Reagents for Selective Metalation, Deprotonation, and 1,2-Additions.
Transformative reagents for selective metalation, deprotonation and nucleophilic additions have allowed for unprecedented selective converstions to reactive intermediates within a molecule which contains sensative functionalities under mild reactions.
