Abstract

Pb (OAc) 4(CH3) 3SiN3 reacts with simple nucleophilic olefins to form mostly diazides and azide-acetoxy compounds, 2 while with steroidal olefines α-azidosteroidketones3 are afforded. Contrary to this result the title reagent reacts not only with nucleophilic but also with electrophilic double-bounds yielding α-azido-carbonyl compounds. Not any azide-acetoxy compound is formed. Compound 14 indicates that activation by an arylgroup is not ...
