The invention provides a method comprising identifying a successful metal-mediated conjugation reaction by analyzing a test mixture for the presence of a conjugation product. The invention provides a two-dimensional approach to reaction discovery in which many catalysts for many catalytic reactions can be tested simultaneously to provide an efficient discovery platform. Reactants and products from the system can be identified using techniques such as gas chromatography, liquid chromatography, mass spectrometry, and combinations thereof.

Synthesis of heterocycles from 1,2-diarylalkene derivatives through electrosynthesis under metal- and oxidant-free conditions has been discovered. Cathodic reduction of 2-alkenylbenzoic acid or anodic oxidation of 2-alkenylbenzamide, 2-alkenylphenol and 2-alkenylaniline leads to the formation of reactive radical intermediates which afford corresponding phthalide, isochroman-1-one, isoindolin-1-one

A remote catalytic reductive sp(2.) C-H carboxylation of arenes with CO2 (1 bar) via 1,4-Ni migration is disclosed. This protocol constitutes the first catalytic 1,4-Ni migration reported to date, thus offering new vistas in the Ni-catalyzed reductive coupling arena while providing an unconventional new platform for incorporating electrophilic sites at remote sp(2) C-H linkages.
