| titleOfInvention | Process for preparing bifunctional z-stilbene compounds, new bifunctional z-stilbene compounds and their use for preparing polymers |
| abstract | Bifunctional stilbene compounds of the formula containing at least one Z-configured stilbene group are made by using compounds of formula with an acetylene of the formula HC≡C-R⁴ (III), in the presence of a palladium catalyst and a base at temperatures of 30 to 160 ° C, the obtained compounds in the presence of a base in compounds of the formula transferred, then the compounds of formula (IV) with compounds of formula in the presence of a palladium catalyst and a base at temperatures of 30 to 160 ° C, then the acetylene compounds obtained in the presence of catalysts with hydrogen or with other reducing agents to Z-stilbene compounds of the formula reduced and the functional groups D and D¹ in the above-mentioned functional groups Z and Y of formula (I) converted in a known manner or the Z-stilbene compounds of the formula (VI) in the case that D and D¹ are at least one bromine atom with compounds of the formula H₂C = CHR⁷ (VII), in the presence of a palladium catalyst and a base at temperatures of 30 to 160 ° C and the functional groups D, D¹ and D² in the functional groups Z and Y of formula (I) leads in the usual manner or the compounds of the formula (IV) with compounds of the formula in the presence of a palladium catalyst and a base at temperatures of 30 to 160 ° C, then the acetylene compounds obtained are reduced in the presence of catalysts with hydrogen or with other reducing agents to corresponding Z-stilbene compounds and then the functional groups D into the functional groups Z and Y of formula (I) transferred in known manner. |
