The reaction represents an obvious example showing that the photochemical approach is effective to offset such an entropic cost, and thereby to drive thermodynamically uphill addition reactions. Moreover the present reactions are highly expedient from the synthetic view point, being transition-metal-catalyst-free, scalable, highly atom economical, and regioselective. The product amines can be converted
An intermolecular radical–radical cross-coupling reaction of secondary and tertiary amines with aryl ketones and aldehydes has been developed using visiblelightphotoredoxcatalysis. This reaction provides an efficient and straightforward approach to some useful 1,2-amino alcohols in moderate to good yields under mild conditions.
