封面介绍A nickel-promoted electrochemical reductive cross-cou-pling to access functionalized and substituted gem-di-fluoroalkenes is reported by Chang, Wang, Lu, and Fu on page 147. Alkyl radicals can be generated by decar-boxylation of redox-active esters or dehalogenation of alkyl halides under mild electrochemical reduction con-ditions and obviates the use of stoichiometric amount metal powder or organic reductants.

封面介绍Chitosan is obtained by deacetylation of chitin and con-tains a large number of hydroxyl and amino groups. Based on chitosan supported copper catalysts, various types of organic reactions were reviewed by Zhang, Li and Zhu on page 33, mainly involving the construction of C—C bonds, C—X bonds, click and oxidation/reduction reactions. It would provide useful information for the researchers engaged in chitosan and related fields in the future.
