Iridium-Catalyzed Enantioselective Allylic Substitution of Vinylcyclopropanes by Carboxylic Acids

open access: yes, 2023
An efficient method for a highly regio- and enantioselective allylic substitution of vinylcyclopropanes using carboxylic acids as oxygen nucleophile via iridium catalysis has been developed.

Sol‐Gel‐Syntheses and Structural as well as Electrical Characterizations of Anatase‐ and Rutile‐Type Solid Solutions in the System IrO2−TiO2

open access: yesChemistryOpen, 2023
This paper describes solid solutions in the quasibinary oxide system iridium‐titanium IrO2−TiO2 with rutile and anatase crystal structures. Based on X‐ray diffraction evaluations using Rietveld refinements, changes of lattice parameters were determined ...

Iridium-Catalyzed Enantioselective Ring Opening of Alkenyl Oxiranes by Unactivated Carboxylic Acids

open access: yes, 2022
An iridium-catalyzed enantioselective ring-opening of alkenyl oxiranes by unactivated carboxylic acids has been developed. The reaction undergoes at ambient conditions between an in-situ-generated chiral iridium-π-allyl complex and carboxylic acids to ...
