Abstract
Abstract A route for the construction of all‐carbon tetra‐substituted olefins through visible‐light promoted coupling of diazo compounds with iodonium ylides was developed. A wide range of all‐carbon tetra‐substituted olefins was obtained in moderate to good yields. The synthetic values of the current method were further approved by the synthesis of natural isolates modified alkenes and the successful transformation of final olefins into important heterocycles. magnified image
