Difluoro(soselenocyanato)phosphine has been prepared by reaction of bromodifluorophosphine with silver(I) isoselenocyanate. Its n.m.r., photoelectron, and i.r. spectra are reported. The low-frequency vibrations of the related compounds P(CN)F2, PF2(NCO), PF2(NCS), and PF2(NCSe) have been studied in the far i.r. with gas-phase samples. With B2H6, PF2(NCSe) forms a complex formulated as PF2(NCSe)·BH3;
二氟(硒代氰基氨基)膦是通过溴代二氟膦与异亚硒酸银(I)反应制得的。报告了其nmr,光电子和红外光谱。在远处的气相样品中,已经研究了相关化合物P(CN)F 2,PF 2(NCO),PF 2(NCS)和PF 2(NCSe)的低频振动。PF 2(NCSe)与B 2 H 6形成配合物,称为PF 2(NCSe)·BH 3。报告了该配合物的1 H,11 B,19 F和31 P nmr数据。
