本文报道了一种选择性Meerwein-Ponndorf-Verley(MPV)型还原体系。在Sm(OCH2R)3(5%)/RCH2OH/4A molecular sieves(MS 4A) (R=CH3, CH3CH2)催化下, 该体系对醛、酮羰基具有优良的选择性还原能力, 能够选择性的还原醛羰基, 而对酮羰基的还原呈惰性。

关键词: 催化, 还原, 选择性, 醛, 酮, 烷氧基钐

This study reports that Sm(OCH2R)3(5%)/RCH2OH/4A molecular sieves (R=CH3, CH3CH2) are efficient catalysts for the chemoselective Meerwein-Ponndorf-Verley (MPV) type reduction of aldehydes in presence of ketonic carbonyl groups.

Key words: CATALYSIS, REDUCTION, SELECTIVITY, ALDEHYDES, KETONE
