The economical and accessible CF3SO3H successfully catalyzed homogeneous O–H and S–H bond insertion reactions between hydroxyl compounds, thiols and diazo compounds under metal- and ligand-free conditions.

A facile and efficient strategy for the synthesis of 1,4-dihydropyridazines and pyridazines through I2-promoted [4+2] cycloaddition of hydrazones with enaminones has been developed. The switch in selectivity is attributed to...

Arylboronates and arylated heteroarenes are ubiquitous scaffolds in materials science, organic synthesis, and drug discovery. Visible light-induced borylation and arylation of small organic molecules is a promising protocol in contemporary...
