Solid-state radical reactions of 1,3-cyclohexanediones with in situ generated imines mediated by manganese(III) acetate under mechanical milling conditions.

Under solid-state conditions, manganese(iii) acetate-mediated radical reactions of 1,3-cyclohexanedione and 5,5-dimethyl-1,3-cyclohexanedione with in situ generated imines proceeded efficiently by mechanical milling at room temperature and good to excellent yields were achieved.
