N,N-Dibenzyl-O,O'-dimethyl thio­phosphate

The P atom in the title compound, C₁₆H₂₀NO₂PS, is bonded in a distorted tetra­hedral P(S)(O)₂N environment with the bond angles at the P atom in the range 99.37 (7) to 115.68 (5)°. The angles at the amido N atom (with bond-angle sum of 357.8°) confirm its sp² character. The C-O-P bond angles are 119.78 (11) and 119.39 (12)°.

N,N,N′,N′-Tetra­benzyl-N′′-(2,6-difluoro­benzo­yl)phospho­ric triamide

In the C(O)NHP(O) fragment of the title compound, C₃₅H₃₂F₂N₃O₂P, the P—N bond is longer and the O—P—N angle is contracted compared with the other two P—N bonds and O—P—N angles. The P atom adopts a distorted tetra­hedral environment and the phosphoryl and carbonyl groups are anti with respect to each other. The two tertiary N atoms of the dibenzyl­amido groups show sp² character with a slight deviation from planarity. In the crystal, pairs of N—H...O(P) hydrogen bonds form inversion dimers.
