Compositions and methods of promoting organic photocatalysis

A method of promoting reaction of at least one reagent, the method comprising:

• irradiating with electromagnetic radiation the at least one reagent in the presence of an organic compound, or a salt or solvate thereof, selected from the group consisting of:
• wherein:
