sodium analogues resulted in the formation of imines. The reaction pattern is given
in Scheme 42. The reason of this behavior was explained via an in situ generated
manganate complex during the reaction. The formed potassium-manganate reacted
about 40 times faster with the formed imine than the sodium-manganate, forming the
amine product [69].

Besides C-N bond formation reactions, the construction of C-C bonds is of great
interest in organic chemistry. Within this context, the β-alkylation of secondary
