N-[Bis(dimethylamino)phosphinoyl]-2,2,2-trichloroacetamide

Abstract

In the title compound, C6H13Cl3N3O2P or CCl3C(O)NHP(O)(N(CH3)2), the phosphinoyl group is synclinal to the carbonyl group and acts as an acceptor for an inter­molecular N—H⋯O hydrogen bond from the amide group as the donor.

Different orientations of C=O versus P=O in P(O)NHC(O) skeleton: the first study on an aliphatic diazaphosphorinane with a gauche orientation

“…General methods and materials 1 H, 13 C, 1 H-13 C HSQC, 19 F, 31 P{ 1 H} NMR spectra were recorded on a Bruker Avance DRS 500 spectrometer. 1 H and 13 C chemical shifts were determined relative to TMS, and 31 P and 19 F chemical shifts, respectively, relative to 85% H 3 PO 4 and CFCl 3 as external standards.…”

“…Some researchers have employed the anionic form [P(O)NC(O)] -to obtain compounds with a non-anti orientation [8] and better donority properties [9]. Despite the numerous structures reported in this series [10][11][12][13][14][15][16][17][18][19], there are a few neutral structures with synclinal orientation [2,5,[13][14][15][16][17]19]. Here, we study on two new compounds with different orientations of C=O versus P=O.…”

“…The phosphorus atoms have a distorted tetrahedral configuration with the bond angles in the range of 101.29(12)The phosphoryl and carbonyl groups adopt an anti position in 2, whereas they are in a gauche situation in 1. Many phosphoric triamides of the type RC(O)NHP(O)[NR 1 R 2 ] 2 have been investigated structurally[1, 2, 5-7, 10, 11, 13-19, 27-55]; however, the nonanti orientation has been observed for a few molecules[2,5,[13][14][15][16][17][18][19]. In Tables S1 and S2 (Supplementary material), some structural parameters of selected molecules with different conformations are gathered.…”

“…[30,31] The sodium salts NaL 1 and NaL 2 were prepared by reaction between equimolar amounts of sodium methylate and HL 1 or HL 2 in methanol medium and were used for preparation of complexes without isolation from the reaction mixture.

“…In this regard, much effort has been devoted to the coordination chemistry of tetradentate and hexadentate Salen-like 3d-4f heterobin-Combining 3d and 4f metals in one molecule, we have tested the ability of the system to catalyze the intramolecular transesterification of 2-(hydroxypropyl)-p-nitrophenyl phosphate (HPNP), which has been extensively employed as an RNA model substrate. [30,31] For the synthesized complexes, an intense asymmetric broad band is observed in the region of 1605-1655 cm -1 , which can be related to the superposition of the valence vibrations of ν(CO) [from (L 1 )or (L 2 ) -] and ν(CN) (from the Schiff bases) (Table S1). Various phosphoesterases are known to contain one or more 3d-metal ions within their active site.…”
