Nickel(0)-Catalyzed Heck Cross-Coupling via Activation of Aryl C–OPiv Bonds
摘要:
Using a Ni(dppf) catalyst generated in situ, Heck cross-coupling of aryl pivalates with a variety of olefin partners has been accomplished. This method represents one of the first examples of a C C cross-coupling via activation of a strong C-O bond with a nonorganometallic coupling partner. It enables the transformation of phenol-based substrates into styrenyl products without generation of a halogenated byproduct or the use of expensive triflate groups.
This invention relates to deuterated compounds that are useful in electroluminescent applications. It also relates to electronic devices in which the active layer includes such a deuterated compound.
