Catalytic aerobic oxidative decarboxylation of α-hydroxy-acids. Methyl mandelate as a benzoyl anion equivalent
摘要:
The monomeric square-planar cobalt(III) complex of bis-N,N'-disubstituted oxamides catalyses the oxidative decarboxylation of alpha-hydroxy acids with molecular oxygen/pivalaldehyde with very good yields. This reaction offers an interesting alternative in the use of methyl mandelate as a convenient benzoyl anion equivalent. (C) 1998 Elsevier Science Ltd. All rights reserved.
