  and secondary alcohols with methanol has been achieved by using bis-N-heterocyclic carbene iridium (bis-NHC-Ir) complexes. Broad substrate scope and up to quantitative yields were achieved at low catalyst loadings with only hydrogen and water as by-products. The protocol was readily extended to the β-alkylation of alcohols with several primary alcohols. Control experiments, along with DFT calculations

  醇的甲基化非常重要，因为大量的生物活性和药用醇都含有甲基。在这里，通过使用双-N-杂环卡宾铱（双-NHC-Ir）配合物实现了伯醇和仲醇与甲醇的高效β-甲基化。在仅氢和水作为副产物的低催化剂负载下实现了广泛的底物范围和高达定量的产率。该协议很容易扩展到β- 醇与几种伯醇的烷基化。对照实验以及 DFT 计算和晶体学研究表明，配体效应对其优异的催化性能至关重要，为与简单醇进行更具挑战性的格尔伯特反应提供了线索。

  An efficient one-pot synthesis of optically active β-alkyl-substituted alcohols through a tandem copper-catalyzed asymmetric allylic alkylation (AAA) with organolithium reagents and reductive ozonolysis is presented. Furthermore, hydroboration–oxidation following the Cu-catalyzed AAA leads to the corresponding homochiral γ-alkyl-substituted alcohols.

• Catalyst recycle in the carbonylation of isobutylphenylethanol to ibuprofen

  In the carbonylation of isobutylphenyl ethanol to ibuprofen in the presence of a phosphine ligand-stabilized palladium catalyst, it has been found that the catalyst complex will precipitate from the organic phase of the carbonylation reaction which includes the ibuprofen product. Precipitation of the catalyst is facilitated by removing the aqueous phase from the reaction and removing any solvents from the organic phase. The precipitated complex catalyst can be recycled without further treatment.
