Imidazolin-2-imine and imidazolidin-2-imine ligands are versatile N donors in transition metal chemistry. Here, we describe the synthesis and characterization of (arene)Ru complexes with these ligands. Simple adducts of the type [(p-cymene)Ru(L)Cl-2] (L = ...

The condensation of multiple building blocks in a ball mill allows molecular cages with a size up to 3.1 nm to be built. ...

In the course of this thesis, two chemically very different topics are going to be discussed. The first part will cover the chemistry of borophosphonate and borophosphate cages, with regard to their application as building blocks for network structures or ...

A versatile and experimentally facile procedure for the synthesis of borophosphonate cages of the general formula [tBuPO3BR′]4 is described. The method involves heating of tert-butylphosphonic acid with a boronic acid in toluene to give borophosphonates in ...

A synthetic procedure for the synthesis of two molecular borophosphate cages is described. Heating of ethyl phosphate with phenylboronic or 4-formylboronic acid in toluene gives [6+6] condensation products of the general formula EtOPO3BAr. Crystallogr ...

The dinuclear complexes [(p-cymene)RuCl2]2 and [(cyclopentadienyl)MCl2]2 (M = Ru, Rh, Ir) are important starting materials in organometallic chemistry. The standard synthesis of these complexes involves heating of an alcoholic solution of RuIII, RhIII, or ...
