✦ Synopsis

N-~ryl imines from aromatic aldehydes react in benzene with ortho-tertbutylphenoxymaonesium bromide to give 4,4'-arylidenebisphenols 2 through two consecutive para-regiospecific processes whereas N-alkyl imines give mainly oPthOregioselective reactions in the same conditions, producing 2,2'-arylidenebisphenols 1.
