Abstract
Abstract The p ara fluorine in 1-bromo-1-(pentafluorophenyl)ethene (3) is replaced exclusively by sodium methoxide to give 1-bromo-1-(4-methoxy-2,3,5,6-tetrafluorophenyl)-ethene (4) and 2,3,5,6-tetrafluoro-4-methoxyphenylethyne (5). Lithiation of (3) with n-butyllithium and reaction with hexafluorobenzene gave 1,1-bis-(pentafluorophenyl)ethene (7), Ar 3*(8), Ar4*(9), Ar5*(10), and Ar6*(11). (*For an explanation of these notations see text). With magnesium in tetrahydrofuran, the bromo-compound (3) gave an intractable polymeric material, the structure of which, by analogy with the reactions of the lithium compound, is proposed as (6).
