✦ Synopsis

Kinetic selectivity" in the cross condensation of a,B-unsaturated aldehydes and methyl ketones are obtained using 2,4,6-trimethylphenoxymagnesium bromide (2,4,6-TMPOMgBr) in benzene as catalyst. Recent observations made by several authors that organic reactions are subjected to a fundamental cation and solvent effect,' encouraged us to continue our work on ion-pair effects on
