Chloride substituents modify the physical properties of organic compounds in several ways. 12112-67-3, formula is C16H24Cl2Ir2, Name is Chloro(1,5-cyclooctadiene)iridium(I) dimer. They are typically denser than water due to the presence of chlorine, which has a high atomic weight. Quality Control of 12112-67-3.
Peters, Bram B. C.;Zheng, Jia;Krajangsri, Suppachai;Andersson, Pher G. research published 《 Stereoselective Iridium-N,P-Catalyzed Double Hydrogenation of Conjugated Enones to Saturated Alcohols》, the research content is summarized as follows. A study on the effect of additives on the Ir-N,P-catalyzed hydrogenation of enones was described. The combination of benzamide and the development of a reactive catalyst unlocked a novel reactivity mode of Crabtree-type complexes toward C=O bond hydrogenation. The role of benzamide was suggested to extend the lifetime of the dihydridic iridium intermediate, which was prone to undergo irreversible trimerization, deactivating the catalyst. This unique reactivity was then coupled with C=C bond hydrogenation for the facile installation of two contiguous stereogenic centers in high yield and stereoselectivity (up to 99% ee, 99/1 d.r.) resulting in a highly stereoselective reduction of enones.
