Abstract

More usually thought of as a base, the sodium zincate [(TMEDA)center dot Na(mu-TMP)(mu-Bu-t)Zn(Bu-t)] 1 can undergo single electron transfer with TEMPO to give [(TMEDA)center dot Na(mu-TMP)-(mu-TEMPO )Zn(Bu-t)] 2 and [(TMEDA)center dot Na(mu-TEMPO )(2)-Zn(Bu-t)] 3; and with chalcone [PhCOCH=CHPh] gives [{(TMEDA)center dot Na(mu-TMP)Zn(Bu-t)}(2)(mu-OCPhCH=CHPhCH-PhCH=CPh-mu-O)] which contains two chalcone units C-C coupled though their benzylic C atoms.
