Abstract

The present invention generally relates to methods for preparing substituted aromatics via direct C-H, C-O, C-S or C-N bond conversion and methods for synthesizing isotopically labeled substituted aromatics via direct carbon-halogen bond conversion. The invention also relates to an anaerobic catalyst system comprising an acridinium photocatalyst and a nucleophile selected from the group consisting of halides, cyanides and isotopically labeled amines. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Application Serial No. 62 / 812,179, filed February 28, 2019, the contents of which are hereby incorporated by reference in their entirety. [0003] Statement Regarding Federally Funded Research [0004] This invention was made with Government support under Grant Nos. GM120186 and EB014354 awarded by the National Institutes of Health. The government has certain rights in this invention. Background technique [0005] Aromatic fluorination has attracted considerable attention in the development of pharmaceuticals and agrochemicals, leading to an urgent need to develop simple fluorination methods. Although a variety of methods have recently been developed for the formation of 19 F] The cross-coupling method of C-F bond (Lee et al's (2011) "Science (Science)" 334:639-642; Lee et al's (2012) American Chemical Society Journal (J.Am.Chem.Soc. )” 134:17456-17458; Mossine et al.
