The effect of 2,6-dimethyl groups on enolization vs. addition in the reaction of PhMgBr with PhCH2COPh, and also the formation of α-diketone from 2,4,6-Me3C6H2COCl by the treatment with MeMgX and i-PrMgX in the presence of CoCl2, were studied.The results were discussed on the basis of electron-transfer mechanism.
