摘　　要：Hydrozirconation of 1-alkylnylphosphonates gives the organozirconium(Ⅳ) complexes 2 in syn-addition way. Complexs 2 was trapped with NCS, NBS or I2 to afford stereodifined α-halo-1-alkenylphosphonates in moderate to high yields.Hydrozirconation of 1-alkylnylphosphonates gives the organozirconium(Ⅳ) complexes 2 in syn-addition way.
