Contribution to the Chemistry of Borophosphonates and Imidazolin-2-imines

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 ...

(Arene)ruthenium Complexes with Imidazolin-2-imine and Imidazolidin-2-imine Ligands

Rosario Scopelliti, Kay Severin, Justus Tönnemann

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 = ...

Efficient and Rapid Synthesis of Chlorido-Bridged Half-Sandwich Complexes of Ruthenium, Rhodium, and Iridium by Microwave Heating

Rosario Scopelliti, Kay Severin, Zacharias Immanuel Grote, Julie Risse, Justus Tönnemann

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 ...

Molecular Borophosphate Cages

Rosario Scopelliti, Kay Severin, Justus Tönnemann

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 ...

Borophosphonate Cages: Easily Accessible and Constitutionally Dynamic Heterocubane Scaffolds

Rosario Scopelliti, Kay Severin, Laure Menin, Konstantin Zhurov, Justus Tönnemann

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 ...
