Abstract

Breaking with convention, the reaction of the sodium zincate, [(TMEDA)Na(mu-TMP)(mu-(t)Bu)Zn((t)Bu)] with benzyl methyl ether (PhCH(2)OMe) produces exclusively an ortho-zincated intermediate [(TMEDA)Na(mu-TMP)(mu-C(6)H(4)CH(2)OMe)Zn((t)Bu)] instead of the expected "thermodynamic" alpha-metallated product.
