Bis(difluorophosphino) selenide has been prepared by the exchange reactions of PBrF2 and PCLF2 with Se(SiH3)2 and Se(SnBu3)2. It has been characterised by vrbrational, mass, n.m.r., and photoelectron spectroscopy. Spectroscopic results have also been obtained for bis(difluorophosphino) sulphide, prepared by analogous methods. Both compounds react with Brønsted acids to give PF2HSe or PF2HS, and a difluorophos-phine
通过PBrF 2和PCLF 2与Se(SiH 3)2和Se(SnBu 3)2的交换反应制备了双(二氟膦基)硒化物。它的特征是可变光谱,质谱,核磁共振和光电子能谱。通过类似方法制备的双(二氟膦基)硫化物也获得了光谱结果。两种化合物均与布朗斯台德酸反应生成PF 2 HSe或PF 2 HS,以及该酸的二氟膦衍生物。通过与乙硼烷反应生成单硼烷加合物,以及从[Mo(C 7 H 8)(CO)4 ]。后一反应说明了这些化合物作为螯合双齿配体的潜在用途。与氯一起,硒化物产生PCl 3 F 2和PClF 2 Se。
