Pd-Catalyzed C-H Functionalizations of O-Methyl Oximes with Arylboronic Acids

Useful methods have been developed to construct ortho-arylated aryl aldoximes, aryl ketoximes, and fluorenones via Pd(II)-catalyzed direct C-H arylation by using arylboronic acids as arylating reagents based on the analysis of the pathways of direct functionalization of aryl aldoximes.
