In MeCN, the direct or mediated cathodic reduction of unactivated ArBr (Ar = 4-biphenyl, 2-fluorenyl, 9-anthryl) in the presence of an equivalent of PhE- (E = Se, Te) leads to ArEPh in interesting isolated yields (53-74 %) by SNR1 substitution. The electrochemical synthesis of 9-phenylchalcogenoanthracene proceeds in better yields in MeCN than in DMSO. The 4,4′-disubstituted biphenyl PhSeC6H4C6H4SePh was prepared in 46 % yield in MeCN whereas its synthesis by photostimulation in liquid ammonia failed.
