• The title sulfide {2,6-(MeO)<SUB>2</SUB>C<SUB>6</SUB>H<SUB>3</SUB>}<SUB>3</SUB>P=S [abbr. (2,6)<SUB>3</SUB>P=S] reacted with acids to form a novel mercaptophosphonium salt [(2,6)<SUB>3</SUB>P–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)<SUB>3</SUB>P–OH]X. (2,6)<SUB>3</SUB>P=S also reacted with alkyl iodides or bromides under mild conditions to give stable (alkylthio)phosphonium salts [(2,6)<SUB>3</SUB>P–SR]X (R=Me, Et, n-Bu), which reacted with thiols at room temperature in the presence of a catalytic amount of the tertiary phosphine (2,6)<SUB>3</SUB>P to give [(2,6)<SUB>3</SUB>P–H]X and unsymmetrical disulfides.
