2,4'-Dilithiophenylethyne, prepared by treatment of 4-bromophenylethyne with two equivalents of butyllithium, reacts selectively with electrophilic reagents at the 4'-position provided the correct temperature and solvent combination are employed.The successive addition of two different electrophiles gives the 2,4'-dialkylated product in a regioselective manner.
