Paragraph 0101-0106, (2021/08/19)
The invention belongs to the technical field of transition metal catalysis and coupling reaction of biomass alcohol, and particularly relates to a method for preparing alkane in one step through self-coupling and cross-coupling of primary alcohol catalyzed by an N-heterocyclic carbene metal compound. The invention firstly provides a catalyst, namely a homogeneous N-heterocyclic carbene metal compound, for preparing alkane through primary alcohol coupling. The method comprises the following steps: by taking primary alcohol as a reaction raw material, tert-butyl alcohol salt of alkali metal, hydroxide and other strong alkalis as alkalis, the N-heterocyclic carbene metal compound as a catalyst and tertiary alcohol, benzene analogue or long-chain alkane as a solvent, reacting at 80-200 DEG C for 4-24 hours to obtain a corresponding alkane product. Compared with the prior art, the method disclosed by the invention has the advantages that the cheap and easily available biomass alcohol can be used as the starting raw material, the use of toxic phosphine-containing ligands with poor stability is avoided, the reaction selectivity and the yield can be quantified, the operation is simple and convenient, different high-purity alkane products can be obtained only through simple post-treatment, and the method is suitable for industrial amplification and application.

Powerful reduction reactions: Simple organic electron donors, composed solely of the elements carbon, hydrogen, and nitrogen, reduce ground-state benzene rings to their radical anions by electron transfer upon photoactivation (DMF=dimethylformamide).
