Abstract:In the presence of organic bromides, toluene was oxidized photochemically by molecular oxygen, producing benzaldehyde as the major product. A modified procedure using hydrobromic acid and bubbling air also gave benzaldehyde with high efficiency and can be applied for the synthetic purpose. Similarly ethylbenzene gave acetophenone.
In the presence of organic bromides Ph‐Br or Ph‐CH2Br, toluene (Ia) is oxidized photochemically by air or O2 to yield benzaldehyde (IIa) as the major product.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
