Nucleophilic Activation of Elemental Sulfur with Amines and Nucleophilic Heterocycles

Case ID:

This invention describes a process to utilize nucleophiles to activate elemental sulfur.

Existing catalytic methods involve heavy metal components and ultraviolet light. Alternative options also include using free-radicals to catalyze a polymerization reaction. The invention instead has the benefit of generating intermediates with unexplored reactivity, which can be used to bond compounds into a sulfur copolymer.
