The reaction of nitriles with Grignard reagents is a widely applicable synthetic route to ketimines, which by facile hydrolysis give ketones. However, this reaction suffers some limitations. With aliphatic nitriles, a serious complication arises due to the acidity of the {alpha}-hydrogen atom. If strongly basic solvents are used, they compete with the nitrile in formation of an organomagnesium complex. If organolithium reagents are used instead of Grignard reagents, the greater basicity of both lithium reagent and the product ketimine salt causes even more difficulty. We report here a specific, rapid, clean, and high-yield reaction of nitriles to give the corresponding methyl ketones by using the uranium metallacycle 1 in nonbasic solvents.
