Catalyst-free photo-reductions of aromatic olefins and carbonyl compounds

Abstract

We describe herein a catalyst-free, traditional reductant-free strategy for the direct photoinduced hydrogenation or deuteration of aromatic olefins, ketones, and aldehydes with simple bases as the only additives. A broad range of substrates were demonstrated with high yields and deuterium incorporations. Mechanistic experiments indicate a radical mechanism.
