Abstract

Abstract Highly dispersed potassium on alumina (K/Al 2 O 3) acts as a metalating agent towards enolizable compounds and the intermediate organopotassium derivatives can be alkylated with primary alkyl bromides. The reaction conditions are dependent on the substrate. In particular, tetrahydrofuran is the solvent of choice for the metalation of nitriles and aldehydeN, N-dimethylhydrazones at− 60 C and of N-cyclohexyl ketimines at room ...
