Ruthenium complex [RuCl2(CO)3]2 catalyzes the addition of 1,3-diketones to terminal alkynes. We observed C-addition with acyclic 1,3-diketones, whereas the use of cyclic 1,3-diketones systematically led to O-addition reactions.

Acyclic 1,3-diketones undergo Ru-catalyzed reaction with terminal alkynes to yield C-addition products whereas cyclic 1,3-diones give O-addition products under similar conditions.

Carbonylation reactions, such as Heck, Sonogashira, and radical carbonylations, were successfully carried out in a "two-chamber reactor" where carbon monoxide was produced ex situ by the Morgan reaction (dehydration of formic acid by sulfuric acid).
