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
50777-76-9, A mixture of 0.14 g (0.48 mmol) 2-(diphenylphosphino)benzaldehyde and 0.05 g (0.48 mmol) ethyl carbazate was dissolved, by heating, in 25 mL ethanol. pH of the mixture was adjusted to ?4 with a hydrochloric acid. The mixture was heated at 56 ¡ãC for 60 min. The reaction solution was left to stand at room temperature while the colourless crystals separated from the solution. Yield 0.15 g (83percent). Mp 164-166 ¡ãC. IR (vs-very strong, s-strong, m-medium, w-weak): 3253 (w), 3189 (w), 3049 (m), 2974 (w), 1729 (m), 1707 (s), 1550 (s), 1458 (w), 1435 (w), 1385 (w), 1247 (vs), 1178 (w), 1092 (w), 1055 (m), 763 (w), 744 (w), 696 (m), 657 (w), 499 (w). HRMS (ESI) of C22H21N2O2P found for (M+H+) 377.1384, calcd (m/z) for (M+H+) 377.1414.
As the paragraph descriping shows that 50777-76-9 is playing an increasingly important role.
