Abstract

The enolates [(dpp‐bian)(H)]MgOC(=CHPh)CH~2~Ph~2~ (6), [(dpp‐bian)(H)]MgOC(=CPh~2~)CH~3~~2~ (7) and [(dpp‐bian)(H)]Mg(camphor)(py)~2~ (8) were prepared by treating (dpp‐bian)Mg(THF)~3~ (1) with equimolar amounts of dibenzyl ketone, 1,1‐diphenylacetone and camphor, respectively. Single‐crystal X‐ray structure analyses showed these enolates to be five‐coordinate, trigonal bipyramidal magnesium complexes with terminal, nonbridging enolate ligands. In solutions of 6 and 7 the proton, which in the solid‐state is attached to only one of the two nitrogen atoms of the dpp‐bian ligand, is delocalised between both nitrogen atoms.
