Carbon dioxide and related heterocumulenes at zinc and lithium cations: bioinspired reactions and principles

Experimental and theoretical investigations of bio-analogue metal complexes are considered. Inspired by the mode of reaction of the enzyme carbonic anhydrase, these complexes are designed to serve as catalysts/intermediates in the course of the activation of CO2, COS and further heterocumulenes.

Inspired by nature: light driven organometallic catalysis by heterooligonuclear Ru(II) complexes

Light driven intramolecular energy or electron transfer in heterooligonuclear metal complexes emerges as a powerful tool in organometallic catalysis. Construction principles for different applications such as photocatalytic hydrogen production, carbon dioxide reduction and C–C bond formation are reviewed.

Asymmetric self-assembly with atmospheric CO2 fixation of a pentanuclear carbonate NiII complex based on dissimilar building blocks

Formation in basic solution of an asymmetric pentanuclear carbonate NiII complex with a compartmental ligand involves atmospheric CO2 uptake, either by reaction of two slightly different dinuclear precursors that yield its di- and trinuclear “building blocks”, or directly, by spontaneous self-organization of metal and ligand starting materials.

Insertion of CO2 into a palladium allyl bond and a Pd(II) catalysed carboxylation of allyl stannanes

Pincer palladium allyl complexes undergo very fast insertion of CO2 presumably via a cyclic transition state. The insertion can be incorporated in a catalytic carboxylation of allylstannanes.

A cadmium hydroxide complex of a N3S-donor ligand containing two hydrogen bond donors: synthesis, characterization, and CO2 reactivity

A new binuclear cadmium hydroxide complex has been prepared, characterized and found to form a binuclear/mononuclear equilibrium mixture in solution; this complex undergoes reaction with CO2 to form a binuclear cadmium carbonate complex.

Insertion reaction of carbon dioxide into Sn–OR bond. Synthesis, structure and DFT calculations of di- and tetranuclear isopropylcarbonato tin(IV) complexes

CO2 uptake by nBu2Sn(OiPr)2 and [nBu2(iPrO)Sn]2O leads to the selective insertion into one Sn–OiPr bond. Structural characterisation reveals the formation of dimers with terminal isopropylcarbonato ligand. DFT calculations support the experiments.

The telomerisation of 1,3-butadiene and carbon dioxide: process development and optimisation in a continuous miniplant

The process development for a miniplant applying telomerisation of 1,3-butadiene and carbon dioxide in a continuous scale is described. Through repeated optimisation combined with parallel laboratory batch experiments the overall space-time-yield of the plant was enhanced significantly.
