A metal-free oxidative radical cyclization/selenylation of propargylic aryl ethers with diaryl diselenides was developed. This protocol provided an alternative method to synthesize 3-organoselenyl-2H-coumarins via the formation of C?Se bond, C?C bond, and C=O bond in one step. Moreover, a broad range of functional groups (such as halogen, aldehyde, ketone, cyano, and nitro group) were tolerated. (Figure presented.).

A one-pot synthesis of tetrasubstituted acrylaldehydes via difunctionalization of aryl propynyl ethers has been achieved, which involves a trifluoromethylthiolation process and a radical 1,4-aryl migration from oxygen to carbon. The reaction shows excellent conversion of aryl propynyl ethers into trifluoromethyl-containing α,β-unsaturated aldehydes through a radical pathway. (Figure presented.).

On the basis of a study of the O-phenylation of 3-phenyl-2-propyn-1-ol with diphenyliodonium triflate and t-BuONa, a variety of 4-aryl-3-iodo-2H-benzopyrans were prepared in good to moderate yields in one pot from the reaction of 3-aryl-2-propyn-1-ols wit

Borderline metal catalysts, Bi(OTf)3 and Fe(OTf)3, were proven to work as dual activators for alkynes and N,O-acetals via σ,π-chelation, which achieved a new carboarylation reaction of alkynylarenes with N,O-acetals.
