• A Versatile Iridium(III) Metallacycle Catalyst for the Effective Hydrosilylation of Carbonyl and Carboxylic Acid Derivatives
  作者：Yann Corre、Vincent Rysak、Xavier Trivelli、Francine Agbossou-Niedercorn、Christophe Michon

  DOI：10.1002/ejoc.201700801

  日期：2017.9.1

  IrIII metallacycle rapidly and selectively catalyses the reduction of various esters, carboxylic acids, ketones, and aldehydes. The reactions proceed in high yields at room temperature by hydrosilylation followed by desilylation. Depending on the substrate, esters are reduced to alcohols or ethers and carboxylic acids to alcohols or aldehydes.

  通用的Ir III金属环可快速，选择性地催化各种酯，羧酸，酮和醛的还原。该反应在室温下通过氢化硅烷化然后脱甲硅烷基化以高收率进行。取决于底物，酯被还原为醇或醚，而羧酸被还原为醇或醛。
