Concise Generation and Diazo‐Preserving Diversification of β‐Diazoimines
Irradiation of a mixture of vinyldiazo esters and azides with blue light, in the absence of any photocatalyst or additive, generates unconventional β‐diazoimines. Mechanistically, the reaction involves the selective decomposition of vinyldiazo compounds under blue light to form singlet free vinylcarbenes, which und...
