- METHOD OF PRODUCING FLUORINE-CONTAINING CARBONIC ACID ESTER
-
PROBLEM TO BE SOLVED: To provide a novel method of producing a fluorine-containing carbonic acid ester. SOLUTION: In a method of producing a fluorine-containing carbonic acid ester, a compound represented by formula (A1), a compound represented by formula (A2) and carbon dioxide are reacted in the presence of a base thereby producing a fluorine-containing carbonic acid ester represented by formula (A3), where formula (A1) is Ra1-OH, formula (A2) is Ra2-CHRa3-Lv, and formula (A3) is Ra1-O-CO-O-CHRa3-Ra2.

- Thermal desulfurization of (Alkoxymethyl)thiiranes
-
Reaction of (alkoxymethyl)oxiranes with thiourea in methanol has afforded the corresponding thiiranes, and catalyst-free thermal desulfurization of the products has been studied. The major products of desulfurization are alcohols and alkenes, both in the cases of (polyfluoroalkyloxymethyl)thiiranes and their non-fluorinated analogs. Longer alkyl chain in thiiranes favors formation of alcohols over alkenes formation in the course of desulfurization.

- Ozonolysis of alkenes and studies of reactions of polyfunctional compounds: LXV.* Ozonolysis of perfluoro-1-octene in Freon-113
-
Ozonization of perfluoro-1-octene in Freon-113 yields the corresponding ozonide whose catalytic hydrogenation over Pd/C or hydride reduction leads to formation of perfluoroheptanoic acid; the reduction with lithium aluminum hydride gives 2,2,3,3,4,4,5,5,6,6,7,7,7-tridecafluoro-1-heptanol. Ozonization of perfluoro-1-octene in Freon-113 containing excess (≥3 equiv) alcohol affords the corresponding perfluoroheptanoic acid ester.

- Process for functionalizing perfluorohalogenoalkanes
-
The present invention relates to the process of preparing perfluoro functional compounds from a perfluorohalogenoalkane having the general formula: wherein RF is a saturated, unsaturated, straight, or branched chain perfluoroalkyl radical containing 2 to 12 carbon atoms, and X is selected from chlorine, bromine, or iodine, comprising reacting said perfluorohalogenoalkane with a functionalizing reagent in the presence of a metallic couple dispersed in a sulfoxide-type solvent, said metallic couple having the general formula: wherein M1 is metal selected from Group IB, IIA, IIB, or IIIA of the Periodic Table and M2 is a metal having an electrochemical potential such that it can be deposited on metal M1.
