Alkenyl sulfones are commonly found in drug active molecules and natural products,serving as the prima-ry molecular framework for various organic transformations.It is a long-term goal in the field of organic synthesis to explore a simple and efficient new method for synthesis of alkenyl sulfones.In recent years,the employment of sul-fonic acid sources,such as sodium sulfinate,sulfonyl hydrazine,sulfonic acid,sulfonyl chloride and DABSO,has led to the generation of sulfone radicals.These radicals have been utilized in non-metal catalysis,metal catalysis,photocatalysis,and electrocatalysis systems.The functionalization reactions mediated by sulfone radicals have rapid-ly advanced the synthesis of allyl sulfones.In this paper,the main synthesis methods for alkenyl sulfones over the past 10 years are introduced.
