Reaction of Dizincocene with Preservation of the Zn----Zn Bond

Reaction without ZnZn rupture: [${{{\rm {\rm Cp}}{{{\ast}\hfill \atop 2\hfill}}}$Zn2] reacts with a fourfold excess of the strong Lewis base 4‐dimethylaminopyridine (dmap) to unexpectedly form the Lewis acid–base adduct 1, in which both dmap molecules coordinate in a geminal binding mode to only on...

Zusammenfassung:Reaction without ZnZn rupture: [${{{\rm {\rm Cp}}{{{\ast}\hfill \atop 2\hfill}}}$Zn2] reacts with a fourfold excess of the strong Lewis base 4‐dimethylaminopyridine (dmap) to unexpectedly form the Lewis acid–base adduct 1, in which both dmap molecules coordinate in a geminal binding mode to only one zinc atom. Cp*=C5Me5.
