Abstract: The first example of metal-free-catalyzed multicomponent annulation reaction of [60]fullerene has been developed for concise and efficient construction of novel [60]fullerene-fused 1,2-tetrahydrocarbazoles. Using inexpensive and readily available I2 as a catalyst, [60]fullerene, ketones, and indoles… read more here.

DOI: 10.1039/c7ra05487d
Abstract: A simple and directed synthetic strategy starting from 2-alkynylarylketones was developed for the construction of various indenones under metal-free and water-assisted conditions. This intramolecular cyclization reaction could well tolerate a wide range of functional groups,… read more here.

DOI: 10.1039/c8py00819a
Abstract: A series of methylthio-substituted poly(ethene–ketone–arylene–ketone)s were synthesized by metal-free catalyzed copolymerization between aromatic diynes and dimethyl sulfoxide (DMSO). The copolymerization can be easily carried out under catalysis by I2 and BF3·Et2O in N,N-dimethyl formamide at… read more here.
