Abstract

The Barbier reaction is generally regarded as a one-pot Grignard reaction. Here, the Grignard reaction of cinnamaldehyde is demonstrated to give a 1,2-addition product, while the Barbier reaction of cinnamaldehyde yields a macromolecule with interesting aggregation-induced emission type non-conjugated luminescence properties, which indicates that the Barbier reaction cannot be regarded as a one-pot Grignard reaction.

Abstract

A new type of organic proton donor for the strong-acid/base-free hydrogen evolution reaction is reported, by taking advantage of the electron deficiency of the boron center of borinic acid and the strong affinity and hydrolysis reaction between borinic acid and water with hydrogen ion formation. The borinic acid proton donor exhibits even higher current density than H2SO4 to promote hydrogen evolution performance in DMF.
