ETHERS OF ORTHOFORMS OF HYPOPHOSPHOROUS, HYPODIPHOSPHOROUS AND PHOSPHORIC ACIDS AND DESIGN OF STRUCTURES IN CHEMISTRY OF PHOSPHORUS-ORGANIS COMPOUNDS (POC) ON THEIR BASE

The new section of the chemistry of phosphorus-organic compounds devoted to the organic derivatives of the orthoforms of hypophosphorous and hypodiphosphorous acids has been created. The section includes the general method for restoration of the phodphorus - halogen connection, development of the method for synthesis of the early unknown dialkoxyphosphines, dialkylaminoalkoxyphosphies, alkylthionhypophosphines, alpha-ketophosphonites and phosphorus(111) reduced formals. The method for soft phosphorylation of the electrophilic bonds with use of the ethers of the orthoform of hypophosphorous acid has been developed. The preparative synthesis method of the phosphorylated formals with four-coordinated phosphorus atom in the molecule has been proposed. The new reaction of the hydrospirophosphoranes with mercury-oxocompounds and also the new re-groupping of the hydrospirophosphoranes into the corresponding phosphoranes have been found, the radical process mechanism has been substantiated. The method for synthesis of the alkoxyspirophosphanes from alkenyloxyspirophosphoranes and also the ways for synthesis of the 2-alkoxy- and 2-dialkylamino-1,3,2-dioxaphospholenes on base of the reaction of disyl oxyalkens and chloranhudrides of the three-coondinated phosphorus acids have been developed. The study of the reactivity in the 1,3,2-dioxaphospholenes permitted to synthesize the cyclic vinyl ethers of the orthoform of hypophosphorous acid.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
