Watch the recordings here on Youtube! This reaction is not useful in actual organic synthesis because of its different by‐products. The mechanism begins with coordination of the ester to the Lewis acid, followed by a rearrangement which generates an electrophilic acylium cation. For polyamides and polyesters (biodegradable polymers) the most important photolytic reactions are the Norrish I and II reactions. Looks like you’ve clipped this slide to already.
