Kalite:
a palladium catalyst was shown to promote the intramolecular cycloaddition of the methylenecyclopropane with an electron-deficient alkyne to yield a methylenecyclopentane.
on montre qu'une catalyse par le palladium favorise la cycloaddition intramoléculaire du méthylènecylopropane, avec un alkyne déficient en électron, pour donner un méthylènecyclopentane.
