On October 26, 2016, Moon, Patrick J.; Yin, Shengkang; Lundgren, Rylan J. published an article.Recommanded Product: Ethyl 2-(4-(trifluoromethoxy)phenyl)acetate The title of the article was Ambient Decarboxylative Arylation of Malonate Half-Esters via Oxidative Catalysis. And the article contained the following:

We report decarboxylative carbonyl α-arylation by coupling of arylboron nucleophiles with malonic acid derivatives This process is enabled by the merger of aerobic oxidative Cu catalysis with decarboxylative enolate interception reminiscent of malonyl-CoA reactivity in polyketide biosynthesis. This method enables the synthesis of monoaryl acetate derivatives containing electrophilic functional groups that are incompatible with existing α-arylation reactivity paradigms. The utility of the reaction is demonstrated in drug intermediate synthesis and late-stage functionalization.

On September 26, 2022, Wang, Songlin; Jiang, Nan; Peng, Jiali; Yang, Peng; Cui, Chengxing; Niu, Hongying; Zhang, Qiying; Wang, Jianji published an article.Reference of Phenyl Salicylate The title of the article was Efficient Synthesis of Diphenyl Carbonate from CO2, Phenol, and Carbon Tetrachloride under Mild Conditions. And the article contained the following:

Herein, an efficient catalytic system for the direct synthesis of DPC from CO2, phenol, and carbon tetrachloride was developed by using a ZnCl2/copper triflate (Cu(OTf)2) composite catalyst. For the first time, high yield and high selectivity were achieved for DPC synthesis under mild conditions, even at atm. pressure. Carefully designed control experiments and DFT studies indicated that the synergistic activation of Cu(OTf)2 and its anion complex with ZnCl2 for phenol and CO2 led to a remarkably improved catalytic activity through a Lewis acid-assisted catalysis. This study not only provides a new strategy for efficient preparation of DPC but also offers an effective pathway for better CO2 utilization.
