katch wreck"Here we describe a photoredox-enabled functionalized carbon-atom insertion reaction into #indene. We disclose the utilization of a radical #carbyne precursor that facilitates the insertion of carbon atoms bearing a variety of functional groups, including #trifluoromethyl, #ester, phosphate ester, sulfonate ester, sulfone, nitrile, #amide, aryl ketone and aliphatic #ketone fragments to access a library of 2-substituted #naphthalenes"
Ring expansion of indene by photoredox-enabled functionalized carbon-atom insertion - Nature Catalysis
Ring-expanding carbon-atom insertion reactions are currently limited to the installation of few functional groups. Now researchers show the use of a radical carbyne precursor for the insertion of carbon atoms bearing varied functional groups to access 2-substituted naphthalenes from indene.
