Synthesis of Highly Functionalized Triarylbismuthines by Functional Group Manipulation and Use in Palladium- and Copper-Catalyzed Arylation Reactions

Organobismuthines
are an attractive class of organometallic reagents
that can be accessed from inexpensive and nontoxic bismuth salts.
Triarylbismuthines are particularly interesting due to their air and
moisture stability and high functional group tolerance. We report
herein a detailed study on the preparation of highly functionalized
triarylbismuth reagents by triple functional group manipulation and
their use in palladium- and copper-catalyzed C-, N-, and O-arylation reactions.
