Photochemical reaction - Photosensitization, Light Activation ...
One type of photochemical reaction is the dissociation of a molecule into two fragments. Since it is the electrons that provide the bonding forces that hold atoms together into molecules, if the distribution of electrons within a molecule changes drastically, the bonding forces may also change. In photodissociation, also called photolysis, the ...

Photochemical [2+2] Cycloaddition of Alkynyl Boronates
Jul 2, 2023Introduction. Organoboron compounds are one of the most recognized reagents of modern organic synthesis. 1 After the development of efficient Suzuki-Miyaura cross-coupling protocols, compounds bearing -B bonds (i. e., (het)aryl or akenyl boronates) rapidly become highly desirable targets for synthetic organic chemists.Traditionally, these compounds have been prepared via hydroboration, 2 ...
