50777-76-9, 2-(Diphenylphosphino)benzaldehyde is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
The synthesis of the iminophosphine ligand carryingalkoxylsilane moiety (A) was performed through the reactivedistillation of 2-(diphenylphosphino)benzaldehyde (0.500 g)with 3-(aminopropyl)trimethoxysilane (0.255 g) in dry toluene(25 mL). After 5 hours, we obtained a yellow oily liquidby careful removal of toluene under vacuum (87 percent yield).1H NMR (400 MHz, CD2Cl2): delta = 8.8 (s, 1H), 8.02 (s,1H), 7.45-7.27 (m, 12 H), 6.91 (s, 1 H), 3.53 (s, 9 H), 3.46(m, 2 H), 1.68 – 1.60 (m, 2 H), 0.58 – 0.52 (m, 2 H); 13CNMR (100 MHz, CD2Cl2): delta= 158.57, 134.14, 128.79, 65.13,50.82, 24.62, 8.73 ppm.; 31P NMR : (300 MHz, CD2Cl2,ppm) delta= -13.07ppm., 50777-76-9
The synthetic route of 50777-76-9 has been constantly updated, and we look forward to future research findings.
