Epoxidation of alkenes with molecular oxygen and isobutyraldehyde catalyzed by immobilized vitamin B-12 within Al-MCM-41
Vit-B-12/ Al-MCM-41 catalyzed successfully the epoxidation either of cis or trans - stilbene with O-2 as oxidant and isobutyraldehyde as co-reductant with 86-98% reactivity and 97-100% selectivity. Other olefins such as norbornene and styrene undergo epoxidation reaction under similar conditions with good to fair selectivity. Details of the reactions will be presented in this article.
