Some azole derivative phosphoric and thiophosphoric esters
Reaction of spiro[cyclohexane-1, 2-oxazolidine] (I) with phosphorochloridic and phosphorochloridothionic acids gave the corresponding ethers. It did not prove possible to prepare derivatives containing dispiro[cyclohexane-1, 2′-oxazolidine] radicals. Reaction of 2-thio-5, 5-dimethyloxazolid-4-one with diethylphosphorochloridate led to isolation of an alkylation product. 5, 5-Dimethylhydrantoin did not react with chlorides of phosphoric acid under the reaction conditions of these particular experiments.
