A copper-catalyzed primary benzylic and allylic alcohols oxidation system has been developed under air in neat water by use of a water-soluble ligand (pytl-β-CD). The ligand was designed and synthesized via a click conjunction between functionalized β-cyclodextrin (β-CD) and 2-ethinylpyridine.
Organic Electrochemistry: Expanding the Scope of Paired Reactions

Paired electrochemical reactions allow the optimization of both atom and energy economy of oxidation and reduction reactions. While many paired electrochemical reactions take advantage of perfectly matched reactions at the anode and cathode, this matching of substrates is not necessary. In constant current electrolysis, the potential at both electrodes adjusts to the substrates in solution. In principle, any oxidation reaction can be paired with any reduction reaction. Various oxidation reactions conducted on the anodic side of the electrolysis were paired with the generation and use of hydrogen gas at the cathode, showing the generality of the anodic process in a paired electrolysis and how the auxiliary reaction required for the oxidation could be used to generate a substrate for a non-electrolysis reaction. This is combined with variations on the cathodic side of the electrolysis to complete the picture and illustrate how oxidation and reduction reactions can be combined.

Method for preparing 3,4-dimethyl benzaldehyde by efficiently catalyzing pseudocumene
-
Paragraph 0023-0056, (2019/08/20)
The invention belongs to the technical field of polyoxometallate catalysts, and relates to a method for preparing 3,4-dimethyl benzaldehyde by catalytically oxidizing pseudocumene with a polyoxometallate (Keggin type, Dawson type, Silverton type, Waugh type, Lindquist type, Anderson type and the like) catalyst. The polyoxometallate is adopted as the catalyst, and placed in a reactor, then an organic solvent and the pseudocumene are added in sequence, finally an oxidizing agent is added, stirring and reacting are carried out for 12-48 hours at the temperature of 50 DEG C to 80 DEG C, separationis carried out, and the 3,4-dimethyl benzaldehyde is obtained. Compared with the prior art, the method is easy to operate and mild in condition, the method for preparing the 3,4-dimethyl benzaldehydehas atom economy and environmental friendliness, the conversion rate of the pseudocumene and the selectivity of the 3,4-dimethyl benzaldehyde are high, the catalyst has the advantages of being green,efficient, easy to recycle and the like, and application and popularization value is achieved.
