Aerobic oxidation of secondary alcohols via ruthenium-catalysed hydrogen transfer involving a new triple catalytic system
Abstract
Aerobic oxidation of secondary alcohols was performed employing a new triple catalytic system (Ru-catalyst 1, 2,6-di-tert-butylbenzoquinone 2, and Co-macrocycle 3) under a low concentration of molecular oxygen (air : nitrogen is between 1 : 3 and 1 : 20) at ambient pressure.
