A catalyst system consisting of Cp*RuCl(cod)/PPh3 [Cp* = pentamethylcyclopentadienyl, cod = 1,5-cyclooctadiene] for the novel cross-benzannulation of 2 equiv of dialkyl acetylenedicarboxylate with an allylic compound has been developed. As an example

Publikováno v: Journal of the American Chemical Society. 124(24)

Pyranopyrandiones were prepared by a novel ruthenium-catalyzed carbonylative dimerization of cyclopropenones via C-C bond cleavage. For example, treatment of dipropylcyclopropenone with a catalytic amount of Ru3(CO)12 and NEt3 in THF under 15 atm of
