Abstract
The cross‐olefination reaction of donor and acceptor diazo compounds was explored. The use of N‐nosylhydrazones as diazo surrogates and the dependence on silver catalysis were crucial for the reaction development. A variety of (hetero)aryl N‐nosylhydrazones and α‐diazo esters, amides, and phosphonates were compatible, and the functionalized alkene products were afforded in good to high yields with moderate (Z)/(E) selectivities. The experimental and DFT calculation results suggest that the cross‐selectivity is due to selective activation of the silver catalyst for donor diazo compounds.
