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. Category: chlorides-buliding-blocks.
Guerra Faura, Gabriel;Nguyen, Tena;France, Stefan research published 《 Catalyst-Controlled Chemodivergent Reactions of 2-Pyrrolyl-α-diazo-α-ketoesters and Enol Ethers: Synthesis of 1,2-Dihydrofuran Acetals and Highly Substituted Indoles》, the research content is summarized as follows. A catalyst-controlled, chemodivergent reaction of pyrrolyl-α-diazo-α-ketoesters, e.g., I (R = H, Et, Ph, R1 = Me, Bn, Ts), with enol ethers, e.g., 2-methoxypropene, dihydropyran, and (1-ethoxyvinyl)benzene, is reported. While Cu(II) catalysts selectively promoted a [3+2]-cycloaddition to provide pyrrolyl-substituted 2,3-dihydrofuran (DHF) acetals, e.g., II, dimeric Rh(II) catalysts afforded 6-hydroxyindole-7-carboxylates, e.g., III, via an unreported [4+2]-benzannulation. The choice of enol ether proved to be crucial in determining both regioselectivity and yield of the resp. products (up to 91% yield for Cu(II) and 82% for Rh(II) catalysis). Furthermore, the DHF acetals were shown to serve as precursors to 7-hydroxyindole-6-carboxylates (isomeric to the indoles formed from Rh) and highly substituted furans in the presence of Lewis acids. Thus, from a common pyrrolyl-α-diazo-α-ketoester, up to three unique heterocyclic scaffolds can be achieved based on catalyst selection.
