Synthesis, spectroscopic study, X-ray crystallography and ab initio calculations of the two new phosphoramidates: C6H5OP(O)(NHC6H11)2 and [N(CH3)(C6H11)]P(O)(2-C5H4N-NH)2

The first naphthodiazaphosphorinane in the solid phase; syntheses, spectroscopic studies and X-ray crystallography of some new 1,3,2-diheterophosphorus compounds

“…The torsional angles of P-N-C-H axial and P-N-C-H equatorial are about ±70°and ±170°, respectively, obtained from X-ray crystallography of our similar previous structures [23,24]. Therefore, according to the Karplus equation [25], the 3 J(PNCH) = 26.0 Hz is related to the H equatorial atom and for H axial atom the coupling with phosphorus atom was not observed.…”

Phosphoramidates: Molecular Packing and Hydrogen Bond Strength in Compounds Having a P(O)(N)n(O)3-n (n = 1, 2, 3) Skeleton

“…Selecting of a suitable solvent, which triethylamine hydrochloride or the other salt is low-soluble, develops the synthesis of some initial phosphorus-chlorine compounds such as [(CH 3 )(C 6 H 11 )N]P(O)Cl 2 [67], [4-CH 3 C 6 H 4 NH]P(O)Cl 2 [68] [70].…”

“…In compounds having an (N)P(O)(NH) 2 skeleton, three different linear arrangements were observed: a) through P(O)···H-N hydrogen bonds in which one N-H unit doesn't cooperate in H-bonding (NUVROL [107], Scheme 27 and HIVLII [67], Scheme 28), b) through R 2 1 (6) (in [(CH 3 ) 2 [62] and the compound with refcode IKASAP [47], Scheme 29 (bottom)), two latter cases via P(O)···(H-N)(H-N) grouping in which the phosphoryl oxygen atom acts as a double-H acceptor.…”

New phosphoric triamides: Chlorine substituents effects and polymorphism

“…The increasing interests in research on phosphoramidates chemistry in the present years are due to the valuable applications of these derivatives as prodrugs [1][2][3], insecticides and pesticides [4][5][6][7], efficient ligands in coordination chemistry [8][9][10][11], theoretical chemistry [12,13], synthesis [14][15][16][17], and structural study [18][19][20][21][22]. So far, the substituent effects on the structural parameters have been discussed to some extent [23][24][25].…”
