(2,6)3P=S] reacted with acids to form a novel mercaptophosphonium salt [(2,6)3P–SH]X, solution thermolysis of which in the absence or presence of triphenylphosphine resulted in the unusual desulfurization to give the tertiary phosphonium salts [(2,6)3P–OH]X. (2,6)3P=S also reacted with alkyl iodides or bromides under mild conditions to give stable (alkylthio)phosphonium salts [(2,6)3P–SR]X (R=Me, Et
标题硫化物2,6-(MeO)2C6H3}3P=S [缩写。(2,6)3P=S] 与酸反应形成新型巯基鏻盐 [(2,6)3P-SH]X,在三苯基膦不存在或存在下,溶液热解导致不寻常的脱硫,得到叔鏻盐 [(2,6)3P-OH]X。(2,6)3P=S 也在温和条件下与烷基碘或溴化物反应,得到稳定的(烷硫基)鏻盐 [(2,6)3P–SR]X (R=Me, Et, n-Bu),在催化量的叔膦 (2,6)3P 存在下,在室温下与硫醇反应生成 [(2,6)3P-H]X 和不对称二硫化物。
