photo-induced cascade sulfone alkylation/cyclization of 2-isocyanoaryl thioethers is explored. This visible-light-triggered reaction not only occurs under extremely mild reaction conditions but also does not require the presence of a photosensitizer. The photocatalytic process is triggered by the photochemical activity of in situ-generated electron donor–acceptor complexes, arising from the association
探索了 2-异氰基芳基硫醚的光诱导级联砜烷基化/环化。这种可见光触发的反应不仅在极其温和的反应条件下发生,而且不需要光敏剂的存在。光催化过程是由原位产生的电子供体-受体复合物的光化学活性触发的,该复合物是由 2-异氰基芳基硫醚和 α-碘砜的缔合产生的。通过紫外可见光谱、自由基捕获、乔布图和开/关照射实验证实了自由基途径。
