CoCl2 catalysed decarboxylation-oxidation of mandelic acids by molecular oxygen

, p. 62 - 66 (2007/10/03)
A series of mandelic acid derivatives was oxidised by molecular oxygen using cobalt(II) chloride as the catalyst. Benzaldehyde and/or benzoic acid derivatives were obtained in high selectivities, depending on the aromatic ring substitution. Different oxidation mechanisms are operating, depending on the mandelic acid substitution.

Dimethyl sulfoxide (DMSO) reacted with arylaldehydes under basic conditions to afford sulfide 1, β-(benzyloxy)styrene 2 and dialkyl sulfoxide 3, while the reaction of benzophenone with DMSO gave 1,1-diphenylethylene 4, 1,1-diphenyl-2-methylthioethylene 5 and sulfoxide 6 at the same time under the same conditions.
Selective synthesis of cis-α,β-unsaturated sulfoxides and sulfides by the Horner-Wittig reaction with bis(2,2,2-trifluoroethyl)phosphono sulfoxides and aromatic aldehydes

cis-α,β-Unsaturated sulfoxides were predominantly formed in the Horner-Wittig reaction with bis(2,2,2-trifluoroethyl)phosphono sulfoxides and aromatic aldehydes, while the reaction of the corresponding sulfides showed trans- or lower cis-selectivity. The reduction of cis-α,β-unsaturated sulfoxides with tributylphosphine in carbon tetrachloride gave cis-vinyl sulfides with retention of stereochemistry.
