These triazenes serve as unique vinyl cation surrogates. Under acidic conditions, the triazene functionality can be replaced with a variety of groups, including halides, alkoxides, sulfoxides, amides, arenes, and heteroarenes, thus providing efficient access to a pool of chiral polycyclic compounds.asymmetric catalysiscycloadditiondivergent synthesisrutheniumtriazenestext::journal::journal article::research article
