Synthesis of Tricyclohexylphosphonium Bromides from an Air-Stable Phosphine Derivative

Article abstract of DOI:10.1055/s-1989-27198

Reaction of tricyclohexylphosphine-carbon disulfide complex 5 with primary alkyl bromides 4 produces tricyclohexylphosphonium bromides 1 in good yields, making isolation of the phosphine 3 unnecessary.In two cases for 4g, h, rearranged products were obtai
