A highly efficient ruthenium pincer-catalyzed Guerbet-type process for the production of biofuel from ethanol has been developed. It produces the highest conversion of ethanol (73.4%, 0.02 mol% catalyst) for a Guerbet-type reaction, including significant amounts of C4 (35.8% yield), C6 (28.2% yield), and C8 (9.4% yield) alcohols. Catalyst loadings as low as 0.001 mol% can be used, leading to a record turnover number of 18 209. Mechanistic studies reveal the likely active ruthenium species and the main deactivation process.
已开发出一种高效的钌钳形催化的格尔伯特型工艺，可从乙醇生产生物燃料。它实现了格尔伯特型反应中乙醇的最高转化率（73.4%，催化剂用量为 0.02 毫摩尔%），包括大量的 C4（35.8%收率）、C6（28.2%收率）和 C8（9.4%收率）醇。催化剂用量低至 0.001 毫摩尔%即可使用，创下了 18209 的周转数记录。机理研究揭示了可能的活性钌物种和主要失活过程。
