Abstract
Tishchenko reaction of aldehydes in the presence of an amino alcohol-based Ir bifunctional catalyst was developed. The reaction proceeds with 1 mol% of the catalyst and 20-30 mol% of K2CO3 in acetonitrile at room temperature to give the corresponding dimeric esters in good yield.
Key words
aldehydes - esters - hydrogen transfer - iridium catalyst - Tishchenko reaction
