The Ni-Mediated Cyclocarbonylation of Allyl Halides and Alkynes Made Catalytic. Evidence Supporting the Involvement of Pseudoradical NiI Species in the Mechanism
摘要:
We report here on a highly efficient catalytic method to synthesize intermolecularly the cyclopentane skeleton from starting products as simple as allyl halides, alkynes, and carbon monoxide under very mild reaction conditions by means of a substoichiometric amount of iron, acetone, and a catalytic amount of Ni(II) iodide.
