Thiophosphoric acid. Amidothiophosphoric acid. Diamidothiophosphoric acid. Thiophosphoryl amide. 

Trends in v h were used to study solvent properties involving various phosphoryl and thiophosphoryl amides. The marked dependence of Vpo of difluorophosphino esters (59) upon the phase was interpreted in terms of selfassociation differences. ... 

Bemerkenswert ist ferner die Umsetzung von Diphenylthiophosphinsaure-chlorid mit Di-phenyl-thiophosphinsaure-amid-Kalium- bzw. Lithium-Salz, bei der das stark saure Bis-[diphenyl-thiophosphoryl]-amin (91%) entsteht, das in zwei tautomere Formen vorliegen kann1031 ...

Dichlorphosphoryl-(dichlor-thiophosphoryl)-mcthyl-amin entsteht auch durch Kochen von Thiophosphorsaure-dichlorid-(methyl-trimethylsilyl-amid) mit iiberschiissigem Phosphorylchlorid (Ausbeute 42%)47. Analog reagiert Thiophosphorsaure-difluorid-(methyl-trimethylstannyl-amid) mit Pyrophosphorylfluorid zu Difluorphosphoryl-(di-fluor-thiophosphoryl)-methyl-amin (88% Sdp 47°/20 Torr/2,7 kPa)50 ... 

Mit Sulfensaurechloriden erhalt man unter Abspaltung von Alkylchlorid (Alkoxy-amino-thiophosphoryl)-disulfane411 mit Ammoniumsulfid entstehen die Salze der Thiophos-phorsaure-amid-O-ester412. 

Primary phosphorothiosulphenamides may be acylated, and with sodium ethoxide they are converted into trialkyl phosphorothionates. Other reactions of phosphorothiosulphenamides include the loss of sulphur upon treatment with sodium, and translocation of the amino-function when treated with thiophosphoryl halides. Treatment of the acyl chloride (71) with ethyleneimine gives an amide which undergoes ready conversion into the isocyanate (72). ... 

Phosphorus trichloride is the starting material used most frequently for the preparation of the esters, amides and anhydrides of phosphoric and phos-phorothioic acids. It can be oxidised to phosphoryl chloride (4) and, heated with sulfur in the presence of a catalyst, to thiophosphoryl chloride (5) (Perot, 1962). 

The only comprehensive and readily-available surveys of thio- and seleno-phosphonic and -phosphinic acids appear to be those in the compilation by Kosolapoff and Maier which appeared during the 1970s, and those in the Houben-Weyl volumes. Some further information relevant to heterocyclic systems which possess endo- or exo-cyclic phosphorus-sulphur bonds has been surveyed by Mann Gefter has also provided a useful compilation of syntheses and data for unsaturated thiophosphonates and related compounds. As in the preceding chapters concerned with the synthesis of the various classes of phosphonic and phosphinic acids, literature surveys have been presented for individual compounds and the field, as a whole, is surveyed annually". In addition. Hall and Inch reviewed the mechanistic implications of changes in stereochemistry following displacement reactions at phosphorus in cyclic phosphorus(V) esters and amides, and in so doing discussed the reaction s of many such thiophosphoryl compounds. 

Transformation of carbon-oxygen to carbon-sulfur bonds can be carried out with phosphorus pentasulfide. Amides are converted to thio-amides by sonication at 30-40°C for 1-2 h (Eq. 79). In comparison with conventional methods, less reagent can be used, and the reaction proceeds faster at a lower temperature.236 A similar reaction using the Lawesson reagent was reported.237 Phosphorus pentasulfide reacts with disulfides to give a thiophosphorylated product (Eq. 80).238... 

Thionation of Tertiary Amides. Thiophosphoryl chloride and its V. V-dimethylamide derivatives (eq 1) react with amides at elevated temperature to give thioamides in good yield. The reaction is run in an excess of the thiophosphorus compounds. The most efficient of the thionating agents examined is N,N,N,N-tetramethylamidophosphonothioic chloride.
