《Four-Component Borocarbonylation of Vinylarenes Enabled by Cooperative Cu/Pd Catalysis: Access to β-Boryl Ketones and β-Boryl Vinyl Esters》 was written by Yuan, Yang; Wu, Fu-Peng; Xu, Jian-Xing; Wu, Xiao-Feng. Product Details of 625-99-0 And the article was included in Angewandte Chemie, International Edition in 2020. The article conveys some information:
We report here a general four-component synthetic procedure for the preparation of β-boryl ketones and β-boryl vinyl esters. Joint catalyzed by palladium and copper catalysts, borocarbonylative reaction between vinylarenes, aryl halides/triflates, B2Pin2, and carbon monoxide proceed successfully. A variety of synthetically useful β-boryl ketones were synthesized in good to high yields by using aryl iodides as the substrates. It is noteworthy that when aryl triflates were applied as the starting materials, β-boryl vinyl esters were synthesized in a similar manner and with broad functional group tolerance. A rational mechanism for this reaction was also proposed. In the experiment, the researchers used 1-Chloro-3-iodobenzene(cas: 625-99-0Product Details of 625-99-0)
1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Product Details of 625-99-0 Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.
