Sodium Bromide → HCID 13635748, compound

Participants

Reaction Steps

NaBr (0.6 g, 0.006 mol) and NaHCO3 (6.4 g, 0.076 mol) were mixed together with water (60 ml), toluene (250 g) and 4-(cyclohex-1-en-1-yl)-3-methyl butan-1-ol (96 g (0.573 mol, purity: 99% sum of the isomers) at room temperature with continuous stirring. NaOCl (13% w/w aqueous 426.8 g, 0.745 mol) was added to the reaction mass over 2 h. Stirring was continued for another 1 h. The aqueous phase was removed, organic phase was washed with a solution of NaHCO3 and then with water. The organic phase thus obtained was concentrated and crude product purified by fractional distillation to provide 4-(cyclohex-1-en-1-yl)-3-methylbutanal (62.6 g, yield: 66%, GC purity: 95% sum of the isomers).
