-thiophophinates, and -phosphinic amides are formed in fair yield by treating either bis-chloromethyl-phosphinic or-thiophosphinic chloride with alcohols, thiols, or amines in the presence of equivalent amounts of acid binding agents. Unexpectedly, the thiophosphinates show no insecticidal activity and only the β-cumaryl derivative exhibits a low herbicidal activity.
通过在等量的酸结合剂存在下用醇,硫醇或胺处理双-氯甲基-次膦酸或-硫代次膦酰氯,以合理的收率形成双-氯甲基-次膦酸酯,-硫代膦酸酯和-次膦酰胺。出乎意料的是,硫代次膦酸酯没有显示出杀虫活性,只有β-枯基衍生物表现出低的除草活性。
