The present invention addresses the problem of providing a fluorine-containing aromatic polymer; a method for producing the fluorine-containing aromatic polymer; etc. The problem can be solved by: a polymer having a monomer unit represented by formula (1) (wherein Rin each occurrence is independently a halogen atom, NRR(wherein Rand Rare independently a hydrogen atom or an organic group), or an organic group; n1 is an integer of 0 to 4; two Rs that can be present in the ortho-positions may form a ring together with two carbon atoms on the adjacent benzene ring, wherein the formed ring may have an organic group as a substituent; and Lis a single bond, an oxygen atom, a sulfur atom, -L-O&#x2014;, &#x2014;O-L-O&#x2014;, -L-S&#x2014;, or &#x2014;S-L-S&#x2014; (wherein Lto Lare each independently an alkylene group optionally having one or more substituents); etc.

Fluorinated aromatic polymer and method for producing same

An object of the present invention is to enable the synthesis of various fluorine-containing compounds having an organic group at both terminals of their tetrafluoroethylene structure (&#x2014;CF&#x2014;CF&#x2014;). The present invention provides a fluorine-containing complex compound including

Fluorine-containing complex compound, and production method for fluorine-containing organic compound employing same

An object of the present invention is to provide a method that enables the easy and efficient (high yield, high selectivity, low cost) preparation of a fluorine-containing olefin substituted with an organic group or groups from a fluorine-containing olefin. [Solution] The method for preparing a fluorine-containing olefin substituted with an organic group or groups, the method comprising a step of reacting a fluorine-containing olefin with an organic boron compound in the presence of an organic transition metal catalyst containing at least one transition metal selected from the group consisting of nickel, palladium, platinum, rhodium, ruthenium, and cobalt.

Preparation method for fluorine-containing olefins having organic-group substituents

This invention relates to a method of reacting fluoroolefin with an organic magnesium compound in the presence of a catalyst comprising nickel or palladium so as to efficiently produce fluoroolefin, such as TFE, in which a fluorine (F) atom or atoms bonded to the sphybridized carbon atom are substituted with an organic group.
