CRYSTAL AND MOLECULAR-STRUCTURE AND THE ABSOLUTE-CONFIGURATION OF PHENYL-N'-(1-PHENYLETHYL)METHANEPHOSPHONODIAMIDATE

The structural investigation of the product of the reaction of methane phosphonodichloridate with R(+)-1-phenylethylamine and aniline in the presence of triethylamine [3] was performed. The obtained compound C15 H19N2OP (1) Crystallizes in monoclinic system, space group P2(1) with a = 10.466(1) angstrom, b = 6.984(3) angstrom, c = 10.471(2) angstrom, beta = 95.43(1)-degrees, V = 762.0(9) angstrom3. Z = 2, and R = 0.037 . The absolute configuration at the P and C8 atoms was determined by m eans of X-ray crystallography as R(p) and R(c8), respectively.
