DOI: 10.1039/d0cc06212j
Abstract: The cross-dehydrogenative arylation of benzylic C-H bonds with arenes provides straightforward access to synthetically useful 1,1-diarylmethanes, from readily available starting materials. Current approaches suffer from limited substrate scope, requirement for large excesses of alkyl arene… read more here.
