Functionalization of 1,3‐Butadiene Derivatives under Photo/Electrocatalysis.

In recent years, the functionalization of 1,3‐butadiene has become an attractive strategy for constructing allyl compounds with molecular and structural complexity, and the current research focuses on synthetic chemistry and organic synthesis. Compared with the traditional synthesis method, the synthesis methods promoted by photochemistry or electrochemistry represent an environmentally friendly and mild strategy. In this review, the functionalization reactions of 1,3‐butadiene under photochemical/electrochemical processes in recent years are reviewed according to the classification of functionalization systems, with particular emphasis on the corresponding reaction mechanism, which lays a foundation for further exploration of new catalytic methods.
