- Thirunavukkarasu, Vedhagiri S., Donati, Margherita, Ackermann, Lutz
- Organic letters 2012 v.14 no.13 pp. 3416-3419
- alkynes, carbon-hydrogen bond activation, chemical bonding, chemical reactions, chemical structure, fluorescence, pyrans, regioselectivity, ruthenium
- Hydroxyl-assisted oxidative annulations of alkynes were accomplished with an inexpensive ruthenium(II) complex, delivering fluorescent pyrans via highly site selective as well as chemo- and regioselective C–H/O–H bond functionalizations.
