Abstract

Abstract The Suzuki–Miyaura cross-coupling of 2-nitrodiazonium tetrafluoroborate salts with substituted boronic acids is an effective and efficient means of preparing highly functionalized 2-nitrobiphenyls in modest to excellent yield under extremely mild reaction conditions. Cross-coupling of 2-nitrodiazonium tetrafluoroborate salts with ortho-methoxy- and benzyloxyphenylboronic acids was also demonstrated leading to the ortho-ortho-2- ...
