Abstract

A 1-aryl-2 perfluoro (or polyfluoro) phenylethene and its derivative used as fluoric organic luminescent material or electrically conductive polymer is prepared from perfluoro (or polyfluoro) phenylformaldehyde through condensating with toluenesulfonyl diamine, dehydrogenating by sodium hydride, reacting on phase-transfer catalyst to generate perfluoro (or polyfluoro) phenyldiazo, catalytic decomposing by catalyst to generate metal carbene, capturing it by triphenyl (or trialkyl) arsenic, and condensating reaction on aldehide.

Description

Technical field

[0001] The invention relates to the synthesis and application of a 1-aryl-2 perfluoro or polyfluoro phenylethylene and its derivatives. It is based on perfluoro or polyfluorobenzaldehyde as a raw material, through condensation with p-toluenesulfonyl hydrazine to form a hydrazone, and sodium hydride to produce the sodium salt of p-toluenesulfonyl hydrazone of perfluoro or polyfluorobenzaldehyde. In the presence of a transfer catalyst, perfluoro or polyfluorophenyl diazonium is generated on the spot. Under the action of the catalyst, the diazonium compound is catalytically decomposed to form metal carbene and is captured on the spot by triphenyl arsenic or trialkyl arsenic to form arsenic ylide, which then reacts with aldehyde Prepared by condensation reaction. The derivative has some potential industrial applications and can be developed into a new type of fluorine-containing conductive organic polymer and organic light-emitting material.
