A wide variety of 1,4-diketones may be prepared from simple starting materials by using fluoride ion-catalysed Michaeladditions and silica gel-supported permanganate-promoted Nef transformations.
Carbon-Carbon Bond Formation by the Use of Chloroiodomethane as a C<sub>1</sub>Unit. IV. The Mannich Reaction of Ketones by Means of Dihalomethane and Secondary Amine
Treatment of ketones with dihalomethane (CH2Br2, CH2ClI, and CH2I2) in the presence of secondary amine, preferably pyrrolidine, gave the corresponding Mannich base in varing yields depending on the substrate and/or combination of the reagents.
