N,N-DimethylO-p-tolyl phosphoramidocyanidate

Abstract: Key indicators: single-crystal X-ray study; T = 100 K; mean (C-C) = 0.003 Å; R factor = 0.034; wR factor = 0.084; data-to-parameter ratio = 20.1.The P-N bond in the title compound, C 10 H 13 N 2 O 2 P, is shorter [at 1.6104 (15) Å ] than a normal P-N single bond. The N atom deviates slightly from the plane of the three atoms to which it is bonded. The sum of the angles surrounding this N atom is 358 . In the crystal structure, weak C-HÁ Á ÁO hydrogen bonds link molecules into one-dimensional chains along the a… Show more

“…The N(C 2 H 5 ) 2 and morpholine moieties form P-N bonds with their P atoms in compounds 4 and 6 (the other groups linked to their P atoms are similar), so that the anti-AChE activity for 4 is greater than 6. The molecules 1 and 5 (we reported their structures in previous works [11,12]) are different in only one substitutents linked to the P atom. Figure 3 (a 1 and b 1 ) indicates the tetrahedral configuration of the phosphorus atoms where the similar moieties linked to the P atoms are omitted for clarity (only the direct atoms linked to P atoms are shown).…”

“…example, Amiprofos-methyl [O-methyl O-(4-methyl-2-nitrophenyl) N-isopropyl phosphoramidothioate] is a herbicidal organophosphate (Fest & Schmidt, 1982). In our previous work, we reported on the structure of N, N-dimethyl O-p-tolyl phosphoramidocyanidate (Ghadimi et al, 2007). Here, we report the synthesis and crystal structure of the title compound.…”
