摘要: [Cu(dap)2]Cl effectively catalyzes azide addition from the Zhdankin reagent to styrene-type double bonds, and subsequent of a third component benzylic position. In presence light, photoredox cycle is implicated with polar components such as methanol or bromide adding cation. absence by contrast, azidation takes place give diazides. Therefore, regioselective functionalization can be achieved in good excellent yields, switch between light dark controlling degree azidation.
