A process for the selective production of bulky alkyldiarylphosphines and unsymmetrical dialkylarylphosphines comprising reacting a first Grignard reagent having a bulky alkyl group with an aryldichlorophosphine and thereafter and without isolating the resulting bulky alkylarylchlorophosphine intermediate, reacting said intermediate with a second Grignard reagent having a different, less bullky alkyl group or an aryl group to provide the product phosphine.
一种用于选择性生产体积庞大的烷基二芳基膦和非对称二烷基芳基膦的方法,包括将具有体积庞大烷基的第一格氏试剂与芳基二氯膦反应,然后在不分离所得的体积庞大烷基芳基氯膦中间体的情况下,将该中间体与具有不同、较小体积的烷基或芳基的第二格氏试剂反应,以提供所需的膦化合物。
