Andrushko V. Interaction of methylenediphosphines with acrylonitrile and vynilmethylketone contain C=C double bond activated by two trifluoromethyl groups.

Methylenediphosphines and alkenes, activated by trifluoromethyl groups. Investigation of interaction of methylenediphosphines with derivatives of acrylonitrile and vynilmethylketone contain C=C double bond activated by two trifluoromethyl groups. Chemical synthesis, NMR-spectroscopy, X-ray analysis, element analysis. Interaction of methylenediphosphines with alkenes, activated by trifluoromethyl groups was investigated. Unusual fluorination action of fluorocontaining alkenes towards trivalent phosphorus atom was found. Oxidation reactions of phosphinomethylenephosphylides by tetrachloro-o-benzoquinone and hexafluoroacetone was investigated. New type of six membered heterocycles, containing two phosphorus atoms of opposite charge and different coordination number was obtained. Compounds, which contain Р-С-Р structural unit can to apply as bidentat ligands of metalocomplexes for synthesis of catalisators of chemical proceses. Elementorganic and organic chemistry.
