strategies were developed for the synthesis of gem-dihaloenones using alkynes and polyhalomethanes as the starting materials. The methods produce a broad range of gem-dibromoenones and gem-dichloroenones without using photocatalysts or additives, such as bases and oxidants. This is the first example of a photocatalyst-free strategy for the photo-promoted synthesis of gem-dihaloenones. These protocols
