Abstract

The analysis of all known synthesis methods of N-(thio)phosphorylthiómides of the common formula RC(S)NHP(X)R'₂ (1), where R=Alk, Ar; R'=óIk, ór, SAIk, SAr. Alk, Ar; X=O,S has been gave in this report. We worked out the simple and convenient syntheses methods of this class compounds.     

MII-N-diisopropoxythiophosphorylthiobenzamide complexing processes in M2[Fe(CN)6]-gelatin-immobilized matrices (M = Co,Ni, Cu)

Complexing processes in M^II-N-diisopropoxythiophosphorylthiobenzamide binary systems (M = Co, Ni, Cu) in metal(II) hexacyanoferrate(II) gelatin-immobilized matrices upon contact with aqueous–alkaline (pH = 12.0 ± 0.1) solutions of organic compounds have been studied. It has been shown that, in Co^II and Cu^II, the initial act of complexing involves destruction of the Co^II and Cu^II hexacyanoferrates(II) by OH^– ions, leading to formation of the corresponding hydroxides which react with the ligand indicated. In the both systems, successive addition of two ligand molecules per M(OH)₂ fragment occurs and [MB(OH)(OH₂)] and [MB₂] coordination compounds are formed (B^–-a singly deprotonated ligand form). In the Ni^II-N-diisopropoxythiophosphorylthiobenzamide system, the formation of three complexes, (Ni₂BOH)₂[Fe(CN)₆], [NiB(OH)(OH₂)] and [NiB₂] occurs.     

Inversion-Voltammetric Determination of Heavy Metal Ions on Electrodes Modified with Mono- and bis-N-Thiophosphoryl Thiourea

A method is proposed for determining Ni^{2 +}, Co^{2 +}, Cu^{2 +}, Cd^{2 +}, and Pb^{2 +} ions by inversion voltammetry on carbon-paste electrodes modified with N-diisopropoxythiophosphoryl-N'-phenyl thiourea and its derivatives: N,N'-bis-(diisopropoxythiophosphorylamidothiocarbonyl)-1,5-diamino-3-oxapentane, N,N'-bis- (diisopropoxythiophosphorylamidothiocarbonyl)-1,8-diamino-3,6-dioxaoctane and N,N'-bis-(diisopropoxythio- phosphorylaminothiocarbonyl)-1,10-diaza-18-crown-6.     

Thermochemistry of Heteroatomic Compounds XXI: Heat Capacities of Some Derivatives of Methylphosphonic and Dithiophosphorus Acids

The heat capacities of 2,4-dimethyl-2-oxo-(I)-, 2,5,5-trimethyl-2-oxo(II)-1,3,2-dioxaphosphorinanes, methylphosphonic acid (III), O,O-dimethyl(IV)-, O,O-diethyl(V)-, O,O-di-isopropyl(VI)esters of dithiophosphorus acid, 4,5-dimethyl-2-thiono-2-mercapto-1,3,2-dioxaphospholane(VII), and 4-methyl-2-thiono-2-mercapto-1,3,2-dioxaphosphorinane(VIII) were determined using the scanning calorimetry.
