Reactions of substituted 1-alkynylphosphines with Et2Zn catalyzed by the Cp2ZrCl2—EtMgBr system
The reactions of 1-alkynylphosphines with Et2Zn in the presence of catalytic amounts of Cp2ZrCl2 and EtMgBr proceed regio- and stereoselectively to afford (1Z)-alkenylphosphines. The oxidation and sulfonation of synthesized 1-alkenylphosphines with an aqueous solution of hydrogen peroxide or elemental sulfur give (1Z)-alkenylphosphine oxides and (1Z)-alkenylphosphine sulfides, respectively. A plausible scheme for the Zr—Mg-catalyzed 2-zincoethylzincation of 1-alkynylphosphines was proposed.
