Photocatalytic\nBorylation of Imines and Alkenes via\nDecarboxylation of Trimethylamine Carboxyborane: A New Approach for\nGenerating Boryl Radicals

In this study, we investigated the photocatalytic decarboxylation\nof trimethylamine carboxyborane under mild conditions, successfully\ngenerating boryl radicals for subsequent borylation reactions with\nimines and various alkenes. This method exhibited broad substrate\ncompatibility, including the functionalization of biologically relevant\nmolecules. Our findings expand the utility of trimethylamine carboxyborane\nbeyond its role as a carbon-monoxide- and drug-releasing agent, highlighting\nits potential in radical chemistry through decarboxylation. This work\nestablishes a robust foundation for further exploration of the synthetic\napplication of trimethylamine carboxyborane.
