Reaction of dialkyl phosphites with 1,1-dichloronitrosoalkanes

ConclusionsDialkyl phosphites react with 1,1-dichloronitrosoalkanes at 20‡C over 5–6 days to give the corresponding alkylchloroformimlnodialkyl phosphates.

Acid chlorides of O-alkylchloroformimino-O-alkylphosphoric acids

Reaction of 1,1-dichloro-1-nitrosoalkanes with dialkyl chlorophosphites yields acid chlorides of O-alkylchloroformimino-O-alkylphosphoric acids. Hydrolysis of these compounds leads to nucleophilic substitution of the Cl atom at the phosphorus atom and not that in the alkylchloroformimino part of the molecule. The O-alkylchloroformimino-O-alkylphosphoric acids were isolated and characterized in the form of the corresponding ammonium salts.

O-alkylchloroformimino O-alkyl methylphosphonates

ConclusionsO,O-Dialkyl methylphosphonites and O-alkyl methylphosphonites react with 1,1-dichloro-1-nitrosoalkanes to form the corresponding O-alkylchloroformimino O-alkyl methylphosphonates.

Synthesis and molecular structure of o-isopropylchloro-formiminodiphenylphosphinate

ConclusionsDiphenylphosphine reacts with two equivalents of 1,1-dichloro-1-nitrosoisobutane to give O-isopropylchloroformiminodiphenylphosphinate. The molecular structure of this product was determined by x-ray diffraction structural analysis.

Reaction of 2,2,3,3-tetrafluoropropyl dichloro-phosphite with 1,1,2-trichloro-1-nitrosoethane

ConclusionsDepending on the reaction conditions, 2,2,3,3-tetrafluoropropyi dichlorophosphate and 1,1,2-trichloro-1-nitrosoethane give either O-chloromethylchloroformiminodichlorophosphate or O-chloromethylchloroformimino-O-2,2,3,3-tetrafluoropropylchlorophosphate.

Reaction of polychloronitrosoethanes with phosphorous acid derivatives

ConclusionThe reaction of polychloronitrosoethanes with phosphorous acid derivatives results in the formation of the corresponding O-phosphorylated alkylchloroformimines.

Reaction of α-chloronitrosoalkanes with the trimethylsilyl ester of diphenylphosphonous acid

The reaction of α- chloronitrosoalkanes with the trimethylsilyl ester of diphenylphosphonous acid leads to the formation of products of the Allen reaction, namely, phosphorylated oximes.

Reaction of 1,1-dichloro-1-nitrosoalkanes with the acid chloride of S-ethylmethylphosphorous acid in the presence of sulfur dioxide

Abstract1,1-Dichloro-1-nitrosoalkanes react exothermally with the acid chloride of S-ethylmethylphosphorous acid to give O-alkylchloroformiminophosphoranes, which are converted in the presence of SO2 to O-alkylchloroformimino-S-ethylmethylphosphonates.

Reaction of 1, 1-dichloro-1-nitrosobutane with N,N-dimethylamidodichlorophosphite

Conclusions1,1-Dichloro-1-nitrosobutane reacts exothermally with N, N-dimethylamidodichlorophosphite to give N,N-dimethylamidotetrachlorophosphorane and a nitrile oxide. In the presence of SO2,this reaction gives O-propylchloroformimino-N, N-dimethylamidochlorophosphate.

Reaction of 1,1-dichloro-1-nitrosoalkanes with trivalent phosphorus acid chlorides

Conclusions1,1-Dichloro-1-nitrosoalkanes react with trivalent phosphorus acid chlorides not containing a P-O ether bond in the presence of nucleophilic reagents (sulfur dioxide, ethanethiol) to produce phosphorylated alkylchloroformoximes. This is rationalized in terms of intermediate O-alkylchloroformiminoyldichlorophosphorane formation.
