An N-Thiophosphinyl Carboxamide: [O,S] Transposition with Disproportionation and Hydrolysis

Autor: Kenneth E. DeBruin, Eric E. Boros, Susan M. Schelble

Publikováno v: Phosphorus, Sulfur, and Silicon and the Related Elements. 75:151-154

N-Diphenylthiophosphinyl-N-methyl carboxamide (laab) undergoes an uncatalyzed “[O,S]-transposition” in CCl4 to form a 75:25 equilibrium mixture of laab and N-diphenylphosphinyl-N-methyl thiocarboxamide (2aab). This equilib-rium mixture then slowl

A new route to N-monosubstituted thioamides utilizing phosphoramidothionates as reagents for the thioamidation of carboxylic acids

Autor: Kenneth E. DeBruin, Eric E. Boros

Publikováno v: The Journal of Organic Chemistry. 55:6091-6098

Several N-monosubstituted thioamides have been synthesized from the corresponding carboxylic acid chlorides and primary amines by a new procedure. The procedure utilized a commercially available and inexpensive organophosphorus reagent (dimethyl chlo

A New Route to Phosphoryl Thiocarbonyl Mixed Imides - Structure Limitations

Autor: Eric E. Boros, Kenneth E. DeBruin

Publikováno v: Phosphorus, Sulfur, and Silicon and the Related Elements. :139-142

The rearrangement of N-methyl thiophosphoryl carbonyl mixed imides (I, XYP(S)N(Me)C(O)Z) to N-methyl phosphoryl thiocarbonyl mixed imides (II, XYP(O)N(Me)C(S)Z) was studied as a function of substitution on phosphorus (Ia: X = Y = MeO; Ib: X = Ph, Y =

An unusual rearrangement of N-substituted thiophosphoryl carbonyl mixed imides

Autor: Kenneth E. DeBruin, Eric E. Boros

Publikováno v: Tetrahedron Letters. 30:1047-1050

N-Substituted O,O-dimethyl N-benzoyl phosphoramidothioates ( III , R = Me, Ph but not H) undergo an uncatalyzed unimolecular rearrangement in an inert solvent; whereby, the carbonyl oxygen atom exchanges position with the thiophosphoryl sulfur atom (
