Yield:-
Reaction Conditions:
with trichlorophosphate in acetonitrile at -0.16; for 4 h;
Steps:
Tris(morpholin-4-yl) phosphine oxide (3)
For the preparationof 3, a solution of morpholine (12 mmol) in 5 cm3dry CH3CN was added at 273 K to a solution of P(O)Cl3(2 mmol) in 10 cm3 of the same solvent. After stirring for4 h, the precipitated amine hydrochloride salt (OC4H8-NHHCl) was filtered off and the acetonitrile solution of[OH8C4N]3P(O) was used in a reaction with Cu(NO3)2-4H2O in CH3OH under reflux. Single crystals of 3 wereobtained fortuitously from slow evaporation of the filteredsolution of the mentioned reaction at room temperature.M.p.: 184-186 C (187-188 C [19]); IR (KBr): m = 2965,2847, 1456, 1367, 1325, 1296, 1258, 1207, 1130, 1115,1090, 1024, 956, 918, 847, 733, 675, 621, 571, 518,482 cm-1.
