摘要

9, 9-Bis (ethylthio) fluorene (1a) reacted with sodium ethanethiolate in methanol to give 9- ethylthiofluorene and diethyl disulfide suggesting that a C–S bond cleavage occurs by attack of a nucleophile at sulfur if a leaving group is sufficiently stable. The pseudo-first-order rate constans for the reaction of 1a and methoxycarbonyl-substituted 9-ethylthiofluorenes have suggested that the methoxycarbonyl group at 1-position exerts through space interaction ...
