2021年6月10日 · Diphenylphosphine 98%; CAS Number: 829-85-6; EC Number: 212-591-4; Synonyms: HPPh2,Ph2PH; Linear Formula: (C6H5)2PH at Sigma-Aldrich

2023年1月1日 · Six new pincer-nickel complexes with phenyl-bridged phosphinite−imidazoline ligands were successfully prepared and well characterized. Various chiral phosphines were obtained by pincer-nickel catalyzed asymmetric hydrophosphination in 61–92% yields with up to …

1990年1月1日 · The adducts (Me 3 CCH 2) 3 Ga·P (H)Ph 2 and (Me 3 SiCH 2) 3 Ga·P (H)Ph 2 have been prepared as crystalline solids at room temperature and characterized by cryoscopic molecular weight measurements in benzene solution and 1 H NMR, 31 P NMR and IR spectroscopic data.

通过去质子化可把它转变为二苯基膦化物：Ph2PH + nBuLi → Ph2PLi + nBuH ，诸如1,2-双 (二苯基膦)乙烷和1,3-双 (二苯基膦)丙烷之类的膦配体、维蒂希－霍纳尔试剂和季鏻盐的合成通常需要通过二苯基膦的烷基化来实现。 二苯基膦用于合成氨基膦，用作催化剂。 它也可用于制备具有N-杂环卡宾配体作为催化剂的手性Palladacycles。 二苯基膦或诸如二苯基膦钠和二苯基膦锂等二苯基膦化物作为亲核试剂能加成到碳杂原子双键上。 比如在100°C的浓盐酸条件下，二苯基膦能加成 …

1989年7月3日 · A solution of Me2- SnC12 and HPPh2 in 1:2 proportions in the presence of dbu has NMR spectra consistent with the presence of Me2Sn [PPh2]2. Reaction of Me2SnBr2 with dbu and any proportion of HPPh2 results only in the formation of Me2Sn [PPh2]2.

2020年11月11日 · α,β-不饱和酰胺的催化不对称共轭氢膦化反应是通过铜 (I)-PPh2 物质的强亲核性完成的，它提供了一系列带有酰胺部分的手性膦，收率高到极好，具有极好的对映选择性。 此外，不对称二芳基膦（HPAr1Ar2）的动态动力学拆分是通过铜（I）催化的共轭加成与α,β-不饱和酰胺成功进行的，这提供了具有良好到高非对映选择性和高对映选择性的P-手性膦. 1H NMR 研究表明，HPPh2 与铜 (I)-双膦配合物的预配位对于巴顿碱的有效去质子化至关重要。 此外，在过 …

Moreover, the relative stability of the copper (I)- (R,RP)-TANIAPHOS complex in the presence of excessive HPPh2, confirmed by 31P NMR studies, is pivotal for the high asymmetric induction, as the ligand exchange between bisphosphine and HPPh2 would significantly reduce the enantioselectivity.

Reactions of HPPh2 in toluene with CPCs derived from D-camphor methyloxime and 2-tert-butyl-4,4-dimethyl-2-oxazoline provided unique mononuclear Pd (II) complexes with a terminal PPh2 ligand in...

A catalytic asymmetric conjugate hydrophosphination of α,β-unsaturated amides is accomplished by virtue of the strong nucleophilicity of copper (I)-PPh2 species, which provides an array of chiral phosphines bearing an amide moiety in high to excellent yields with excellent enantioselectivity.
