Spectroscopic and crystal structure data of the alkali-, thallium (I) and onic-salts of dimethyl-N-trichloracetylamidophosphate

New organotin(IV) complexes of nicotinamide, isonicotinamide and some of their novel phosphoric triamide derivatives: Syntheses, spectroscopic study and crystal structures

“…Although numerous derivatives of nicotin-and isonicotinamide have been reported in the literature we could not find any phosphoramidate containing these amides. Phosphoramidates including -C(O)N(H)-P(O)-moiety have been used as O-donor ligands in the reaction with various metal ions up to now [4][5][6][7][8][9][10][11][12][13][14][15]. The presence of a peptide group in these compounds causes its diverse biological activity and used as anticancer drugs [16].…”

TetramethylN,N′-(2,2,3,3,4,4-hexafluoro-1,5-dioxopentane-1,5-diyl)bis(phosphoramidate)

“…In the molecule, the carbonyl and phosphoryl groups are in antiperiplanar conformation. The frame O4-P1-N1-C3-O1 is almost flat (the values of dihedral O4-P1-N1-C3 and O1-C3-N1-P1 angles are -169.54 and -0.05°, respectively) as it has been observed for the most CAPh (Gubina et al, 2000;Trush et al 2005). The crystal is composed from polymer chains which are built from molecules linked via intermolecular hydrogen N-H···O=P bonds (Fig.3).…”

“…For the biological and pharmacological properties of carbacylamidophosphate derivatives, see: Adams et al (2002). For details of the synthesis and properties of phosphoramide derivatives, see: Kirsanov & Levchenko (1957); For structural analogues of phosphorylated carbacylamides and their properties, see: Trush et al (2005); Gubina et al (2000). For the synthesis and properties of fluorinated compounds, see: Leontieva et al (2002).…”

Tetraphenylphosphonium salts of N‐thiophosphorylated thiobenzamide, mono‐thioureas or bis‐thioureas

“…Depending on the nature of the atoms X and Y, the anionic ligand exhibits monoor bidentate coordination toward the metal cation, which is situated in the cavity of the macrocycle [1]. Another possible efficient path to prevent the formation of polymeric structures is using large, noncoordinating cations, such as PPh [1,6]. The use of such noncoordinating cations additionally provides the possibility of studying the electronic and geometrical structures of the anions in the absence of coordinating metals, which more or less strongly influence the confirmation or the equilibrium between the three resonance forms depicted in Scheme 1.…”

“…For example it has been found that the structures of the compounds with the formula [M(CCl 3 C(O)NP(O)(OMe) 2 )] depend strongly on the nature of the cation. While with M = Na + dimers were observed in the crystal, for M = Rb + or polymeric chains were found [6]. Potassium salts of thioamides [K(Me 2 CO)PhC(S)NP(S)(OiPr) 2 …”
