Carboxylic acid derivatives via catalytic carboxylation of unsaturated hydrocarbons: whether the nature of a reductant may determine the mechanism of CO2 incorporation?

摘要: Application of CO2 as a renewable feedstock and C1 building block for production commodity fine chemicals is highly challenging but obvious industry-relevant task. Of particular interest the catalytic coupling with inexpensive unsaturated hydrocarbons (olefins, dienes, styrenes, alkynes), providing direct access to carboxylic acids their derivatives. Although not brand new scientific community, it still complete challenge, no truly effective system has been reported date. In this Perspective, we discuss available experimental, theoretical mechanistic data such homogeneously catalyzed carboxylation processes. A special focus placed on understanding key elementary steps some thermodynamic kinetic constraints.
