Synthesis of Tricyclohexylphosphonium Bromides from an Air-Stable Phosphine Derivative 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 obtained.

Ylidefunctionalizedphosphines were tailored supported by computational inverse catalyst design to fit the requirements of mild Hiyamacouplings of aryl chlorides. YPhos/Pd catalyst is highly efficient for the coupling with aryl chlorides in general, and the reaction shows excellent functional group compatibility.
