Oxidation of aromatic aldehydes by Serratia marcescens.
Cell suspensions of Serratia marcescens catalyzed the oxidation of aromatic aldehydes into the corresponding acids in high yield under mild conditions.
متن کاملNickel-Catalyzed Decarbonylation of Aromatic Aldehydes.
We report here the first systematic study of nickel-catalyzed decarbonylation of aromatic aldehydes under relatively mild conditions. Aldehydes with electron donating groups at para and ortho positions are generally successful with our method. For aldehydes with electron-withdrawing groups, significantly higher yields were achieved for ortho-substituted substrates than para ones, probably due t...
متن کاملReaction of benzoxasilocines with aromatic aldehydes: Synthesis of homopterocarpans
Condensation of 2H-benzo[g][1,2]oxasilocines with aromatic aldehydes in the presence of boron trifluoride affords mixtures of cis/trans 2-phenyl-3-vinylchromans with moderate yields. These can be transformed into homopterocarpans, a synthetic group of substances homologous to the natural isoflavonoid pterocarpans.
