Input (English): The alkyl form of these molecules can be treated with triphenylphosphine and ozone to produce nitro compounds, and these compounds can also be reduced to primary amines via the Staudinger ligation. Isocyanates can be produced by treating carbon monoxide with these compounds, and their reactions with alkyl or aryllithium compounds produce primary amines. The Curtius rearrangement pyrolises the acyl variety of these compounds to give isocyanates, and they can be produced by reacting alcohols or olefins with hydrazoic acid. Typically sensitive to shock, the lead forms of these compounds are used in detonators and blasting caps, while the sodium salt is commonly found as an explosive in automobile airbags. FTP, name this functional group which contains three double-bonded nitrogens.
Output (English): Science
