2,2-Dihalocyclopropyl phosphonates and 2,2-dihalocyclopropylmethyl phosphonates are obtained by reaction of vinyl or allyl phosphonates with dihalocarbenes generated under phase-transfer reaction conditions. For the reaction of vinyl phosphonates with dichlorocarbene specific conditions are required; otherwise 3,3,3-trichloropropyl phosphonate is produced by addition of the CCl3 anion to the olefin
2,2-二卤代环丙基膦酸酯和2,2-二卤代环丙基甲基膦酸酯是通过使乙烯基或烯丙基膦酸酯与在相转移反应条件下生成的二卤代卡宾反应而获得的。对于膦酸乙烯酯与二氯卡宾的反应,需要特定的条件;例如,否则,通过将CCl 3阴离子加到烯烃中来生产3,3,3-三氯丙基膦酸酯。
