Diazidated malonamides derived fromamines and diazidated diethylmalonate react with lithiated alcohols through nucleophilic substitutionreactions where azide acts as an unconventional leaving group. Thisdeazidoalkoxylation leads to the formal construction of -acetals, and the remaining azide functionalityis ...

A process for the preparation of aryl-diazide-sulfonic acids by a series of sequential in-situ process steps. The process comprises the nitrosation of a hydroxyarylsulfonic acid; conversion of the nitroso-derivative to a sulfamate which is then diazotized to the diazide. Temperature and pH ...
