Method for preparing biaryl hydrocarbon compound from alcohol compound
-
Paragraph 0024-0026, (2020/02/14)
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.

(Chemical Equation Presented) Radicals derived from N-(α-xanthyl) acetanilides or N-(α-xanthyl)acetylaminopyridines possessing a substituent next to the nitrogen undergo a hitherto undocumented Smiles rearrangement proceeding through a four-membered ring.
Cobalt-mediated Reactions in Synthesis. The Degradation of Carboxylic Acids to Functionalised Noralkanes via Acylcobalt Salophen Intermediates

Arylmethyl- and allyl-carbonylcobalt salophen complexes, e.g. (7), (8), (9), and (22), readily undergo carbon-to-cobalt-bond homolysis and in situ decarbonylation, producing new alkyl radical centres which can be intercepted with oxygen-, nitrogen-, halogen-, sulphur-, and selenium-containing trapping agents leading to functionalised noralkanes.The sequence constitutes a useful, and in some cases more flexible, variant of the classical Hunsdiecker reaction, and amounts to a cobalt equivalent of the Barton radical decarboxylation reaction of carboxylic acids via their corresponding thiohydroxamic esters.In a similar manner, irradiation of the oxy-substituted acylcobalt salen reagents (25) and (26) in the presence of tetramethylpiperidine oxide produces the products (14) and (27), respectively, resulting from homolysis-decarboxylation and alkyl-radical trapping.In the absence of radical-trapping agents, irradiation of (7c) produces (18), and irradiation of (29) leads to the but-2-enolide (32).
