A GREEN APPROACH FOR THE SELECTIVE REDUCTION OF
... Thus, the main route of reduction leads successively to 1e and then 1a products. The formation of the total reduction carbonyl group (CHO CH3) was observed in other cases both in aldehydes [12, 17 – 19] and in ketones [20 – 22]. At higher temperatures or longer in reaction times it tends to become ...
