摘要: Radical conjugate addition onto vinyl sulfones was achieved by means of a convenient, tin-free procedure. This based on the photocatalyzed CH bond activation in aldehydes, amides, ethers and even cycloalkanes using tetrabutylammonium decatungstate (TBADT). The reaction likewise effective for functionalization β-substituted sulfones. products are useful building blocks were obtained satisfactory yields both under artificial UV light sunlight, so demonstrating “green” potential process.
