The transition-metal-catalyzed alc. dehydrogenation to carboxylic acids has been identified as an atom-economical and attractive process. Among various catalytic systems, Ru-based systems have been the most accessed and investigated ones. With our growing interest in the discovery of new Ru catalysts comprising N-heterocyclic carbene (NHC) ligands for the dehydrogenative reactions of alcs., we designed and prepared five NHC/Ru complexes ([Ru]-1-[Ru]-5) bearing different ancillary NHC ligands. Moreover, the effects of ancillary and addnl. ligands on the alc. dehydrogenation with KOH were thoroughly explored, followed by the screening of other parameters. Accordingly, a highly active catalytic system, which is composed of [Ru]-5 combined with an addnl. NHC precursor L5, was discovered, affording a variety of acid products in a highly efficient manner. Gratifyingly, an extremely low Ru loading (125 ppm) and the maximum TOF value until now (4800) were obtained. In the experiment, the researchers used 6-Aminohexan-1-ol(cas: 4048-33-3SDS of cas: 4048-33-3)
6-Aminohexan-1-ol(cas: 4048-33-3) may be used along with glutaric acid to generate poly(ester amide)s with excellent film- and fiber forming properties. It can undergo cyclization over copper supported on γ-alumina and magnesia to form hexahydro-1H-azepine.SDS of cas: 4048-33-3
