The influence of a m- or p-polar substituent in 1-aryl 2-phenyl propanones, on addition reactions with CH3MgBr in ether at 30 deg C has been investigated.The invariability of asymmetric induction as a function of substituent, and the correlation of rate constant ratios with Hammett ? constants (ρ=0.24, r=0.97), are consistent with a four-centre pericyclic concerted mechanism with concomitant departure of a solvent molecule.
