A Reinvestigation of the Reaction Between 2-Methoxy-5,5-dimethyl-1,3,2-dioxaphosphorinan-2-one and 2-Chloro-5,5-dimethyl-1,3,2-dioxaphosphorinan-2-one

The title compounds together give pyrophosphate and methyl chloride probably via a cycle of reactions involving cyclic phosphate diester and hydrogen chloride as carriers; rapid formation of dioxadiphosphetanes from intermediate five-co-ordinate phosphoranes and a slower intermolecular scrambling account for the distributions of 18O observed starting with various patterns of 18O labelling.

Selective P-P and P-O-P bond formations through copper-catalyzed aerobic oxidative dehydrogenative couplings of H-phosphonates

(Chemical Equation Presented) Different copper complexes selectively catalyze the aerobic oxidative coupling of H-phosphonates to afford either hypophosphates and pyrophosphates in high yields with high selectivity (see scheme; tmeda = N, N, N', N'-tetramethylethylenediamine).

METHOD FOR PRODUCING PHOSPHORUS COMPOUND HAVING PHOSPHATE-PHOSPHONATE BOND

A novel process for preparing in a high purity and in a high yield phosphorus compounds having a phosphate-phosphonate bond within one molecule, along with only a small amount of a by-product, without being restricted by the kind of a phosphonate having an alcoholic hydroxyl group which is a raw material, without using a catalyst such as magnesium chloride, but only using a nitrogen-containing basic compound.
