Results and Discussion
Synthesis of halovinylferrocenes
A few years ago we discovered a new reaction for a double carbon–carbon bond formation – the reaction of catalyticolefination. It was shown that the copper
catalyticolefination reaction for the synthesis of ferrocene derivatives. As a result, several well-known and previously unknown ferrocene-containing alkene compounds were obtained.
First, ferrocene carbaldehyde was investigated. It was found, that under usual conditions of the reaction (equal amount of
