Method for preparing biaryl hydrocarbon compound from alcohol compound

The invention provides a method for preparing a biaryl hydrocarbon compound from an alcohol compound. The method comprises the following steps: sequentially adding the alcohol compound, sodium borohydride and iodine (the molar ratio is 1: (2-3): (0.5-1)) into a reaction tube containing acetonitrile solvent, sealing the reaction tube, heating to 100 DEG C, reacting for 10-20 hours, quenching with water after the reaction is completed, drying an organic phase with anhydrous magnesium sulfate, and carrying out rotary evaporation to remove the solvent and obtain a target product. The method has the advantages of convenience in operation, easiness in product separation, high yield, small environmental pollution and the like, is an ideal method for producing the high-energy-density hydrocarbon by utilizing oxygen-enriched biomass raw materials, and has important practical value.

Ni(II)/Al(0) mediated benzylic Csp 3 - Csp 3 coupling in aqueous media

Abstract : The reaction of benzyl bromides and chlorides with aluminium metal powder or foil (1.2 eqv.) in the presence of catalytic nickel nitrate (10 mol%) in water at room temperature resulted in homocoupling to the corresponding bibenzyl products which were isolated in moderate to good yields. In sharp contrast, the same reaction in organic solvents like dichloromethane, dimethylformamide, acetonitrile, methanol and toluene yielded only a trace amount of the desired product. The scope of the reaction was tested with substituents on the aromatic ring such as Me-, Cl-, CN-, F-, NO 2-, Ph- as well as 2 ° benzyl halides. Graphical abstract: The reagent combination of aluminium metal and catalytic Ni(NO3)2 promotes the homocoupling of benzyl bromides and chlorides giving rise to the corresponding bibenzyl products in good to excellent yields. The reaction is greatly facilitated in water and showed good functional group tolerance. Besides the mild reaction condition and bench-friendliness, the present reaction constitutes the first example of aluminium-mediated homocoupling of a halide in water.

A well-defined low-valent cobalt catalyst Co(PMe3)4 with dimethylzinc: a simple catalytic approach for the reductive dimerization of benzyl halides

Herein, we report the first catalytic version of a cobalt-catalysed reductive homocoupling of benzyl halides which proceeds with low catalyst loadings (0.5 to 5 mol%). By synthetizing each cobalt intermediate we demonstrate that reaction proceeds through two single electron transfers (SET) and that dimethylzinc is only involved in the regeneration of the catalytic species.
