A (3+2) cycloaddition between unbiased alkenes and 1,3-dicarbonyls is accomplished by judicious choice of electrode material and electrocatalyst to access dihydrofuran derivatives. A fluorinated porous carbon electrode with appropriate thickness governs unprecedented reactivity. This methodology eliminates the necessity for any stabilizing group within the alkene substrate. This is a rare example of the annulation of unbiased internal and terminal alkenes with cyclic and acyclic -dicarbonyls.
通过明智地选择电极材料和电催化剂，可实现无官能团烯烃与1,3 - 二羰基化合物之间的(3 + 2)环加成反应，从而得到二氢呋喃衍生物。具有适当厚度的氟化多孔碳电极具有前所未有的反应活性。该方法无需烯烃底物中存在任何稳定基团。这是无官能团内烯烃和端烯烃与环状和非环状二羰基化合物环合反应的罕见实例。
