Stereoselective Preparation of (E)-(1,2-Difluoro-1,2-ethenediyl) Bis[tributylstannane] and Stereospecific Synthesis of (E)-1,2-Difluorostilbenes

(matrix presented) The novel bisstannane (E)-(1,2-difluoro-1,2-ethenediyl) bis[tributylstannane] 2 was stereoselectively prepared in a high overall yield through a sequential synthetic route from chlorotrifluoroethylene 1. The synthetic application of this novel bisstannane 2 was exemplified in the Pd(PPh3)4/Cul-catalyzed cross-coupling reactions with aryl iodides, yielding (E)-1,2-diflourostilbenes 3 in moderate to high yields.

PREPARATION METHOD FOR FLUORINE-CONTAINING OLEFINS HAVING ORGANIC-GROUP SUBSTITUENTS

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.

Innermolecular reactions of fluorophenylcarbene inside a hemicarcerand

Photolysis of fluorophenyldiazirine, incarcerated in hemicarcerand 2, affords fluorophenylcarbene, which attacks an aryl unit of the host, leading (after rearrangement) to a fluoromethoxy/phenyltropone derivative of the hemicarcerand. The incarcerated car
