The invention belongs to the technical field of photocatalytic organic synthesis, and in particular relates to a photocatalytic method for generating carbon-carbon bonds, in particular, a carbon atom in methanol and a carbon atom in another alkane (or derivative) molecule are generated under photocatalysis The method for carbon-carbon bond, under the irradiation of easy-to-obtain light source, methanol is dehydrated to remove the oxygen atom therein, generating: CH 2 carbene intermediate, carbene can generate carbon-carbon bond by inserting another methanol molecule And directly converted into ethanol; or insert other non-reactive hydrocarbons to achieve methylation and generate carbon-carbon bonds, extending the carbon chain. The invention realizes a key technological breakthrough in synthesizing green food\materials from green fuel, helps to break the contradiction between green fuel and food supply, and has the potential to make the process of preparing plastic (polyethylene) from air under mild conditions possible . It has the advantages of green sustainability, mild conditions, and wide availability of raw materials. |
