Two typically inert molecules , dinitrogen and carbon dioxide, are activated and combined, with the formation of carbon–nitrogen bonds, using a bis(cyclopentadienyl) hafnium compound. The resulting silyl‐protected carboxy‐hydrazine (central structure) is liberated from the complex upon treatment with the electrophile Me 3 SiI, as illustrated in the cover picture.
