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

“…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].…”

“…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].…”

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

“…Organic derivatives of main group V elements of tetracoordinated phosphorus thioacids with the P(S)SE (E ‫ס‬ As, Sb, Bi) structural fragment appear to have been limited to dithiophosphato and dithiophosphinato moieties [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. 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]. We have now developed a new approach to antimony(III) derivatives of pentavalent phosphorus thioacids having the P(S)SSb structural fragment by the use of 1,3,2,4-dithiadiphosphetane-2,4-disulfides 1a,b and 4.…”

Synthesis, molecular and crystal structure, and properties of 10-propylthio-5,10-dihydrophenarsazine

“…Organothiophosphorus derivatives of trivalent arsenic are used as pesticides [1], analytical reagents [2], and for regeneration of cracking catalysts [2]. Cyclic arsenic(III) dithiophosphates containing the P(S)S-As fragment have been obtained by the reactions of ammonium or sodium dithiophosphates with 1-chloro-2,5,1-dithiarsolane and 2-chloro-1,3,2-dioxarsolanes and -arsenanes [1,3,4].…”
