Application
Within heteroarene platforms, DAAS-Na allows for the direct introduction of a difluoroalkyl chain carrying an azide group, which is designed for the purpose of bioconjugation. Through a Huisgen cycloaddition (a "click" reaction), the azide moiety can then be reacted with a terminal alkyne that is bound to a functional molecule such as biomacromolecules. This effectively allows for a covalent linkage between a heteroarene and any target molecule, for example, between a heteroarene-containing drug and an antibody. This reagent was developed by the Baran Group and is one of several reagents for the direct alkylation of heterocycles.

A general C-H functionalization method for the tagging of natural products and pharmaceuticals is described. An azide-containing sulfinate reagent allows the appendage of azidoalkyl chains onto heteroaromatics, the product of which can then be attached to a monoclonal antibody by

Radical addition processes can be ideally suited for the direct functionalization of heteroaromatic bases, yet these processes are only sparsely used due to the perception of poor or unreliable control of regiochemistry. A systematic investigation of factors affecting the regiochemistry
