Alkylenedithiophosphate derivatives of arsenic(III), antimony(III) and bismuth(III)

Reactions of dithioxo‐1,3,2λ 5 ,4λ 5 ‐dithiadiphosphetanes with arsenic derivatives containing the As‐O, As‐S, and As‐N bonds

“…The 1 H NMR spectra were taken on a Bruker MSL-400 (400 MHz) spectrometer and a Varian T-60 (60 MHz) spectrometer in C 6 D 6 or CDCl 3 with (Me 3 Si) 2 O as an internal reference. The IR spectra were obtained in KBr pellets with an UR-20 infrared spectrophotometer and a Bruker IFS 113v spectrometer.…”

“…Arsenic esters of pentavalent phosphorus thioacids with the P(S)SAs central structural fragment are known to possess some properties of practical use [1,2]. The common methods of synthesizing arsenic(III) dithiophosphates are usually based on the reactions of corresponding dithiophosphoric acids or their salts with arsenic(III) halides or oxides [1][2][3][4][5][6][7].…”

“…The common methods of synthesizing arsenic(III) dithiophosphates are usually based on the reactions of corresponding dithiophosphoric acids or their salts with arsenic(III) halides or oxides [1][2][3][4][5][6][7]. We recently developed alternate methods for the synthesis of S-organoarsenic(III) esters of tetrathiophosphoric and trithiophosphonic acids directly from phosphorus sulfide (P 4 S 10 ) and 1,3,2,4-dithia- diphosphetane-2,4-disulfides [8].…”

Reactions of dithioxo-1,3,2?5,4?5-dithiadiphosphetanes with antimony(III) alkoxides

“…Bands of small intensity present in the region m 386 cm ‫1מ‬ in the IR spectra of 3a (Table 3) are mainly due to the P-S-Sb valence vibrations, such as those found for antimony(III) dithiophosphates [5,6,8]. Bands in the region m 619-624 cm ‫1מ‬ are assigned to the Sb-OC valence vibrations of two alkoxy groups that remain attached to the antimony atom of 3a,b [18].…”

“…We deemed it to be necessary to synthesize new types of organothiophosphorus compounds with the P(S)SE structural fragment with widely varied substituents on the phosphorus atom in order to develop a series of fundamental studies, such as chemical behavior, complexation, influence of heteroatoms in the fragment P(S)SE, tautomerism, conjugation, stereochemistry, etc. Different modes of bonding of dithiophosphato and dithiophosphinato moieties (e.g., monodentate, bridging/chelating, bidentate) in the complex formation with antimony have been elucidated by physicochemical techniques [2,[5][6][7][8][11][12][13]15]. Antimony(III) dithiophosphates and dithiophosphinates have been obtained by the reactions of dithiophosphoric and dithiophosphinic acids, or their salts, with antimony(III) oxides, halides, acetates, and triphenylantimony [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”
