WebHowever, the thiol-ene reaction has recently attracted researchers in other areas of synthesis due to the recognition of its “click” characteristics, vide infra.There are several features associated with the thiol-ene reaction that make it a particularly attractive, facile and versatile process. Firstly, such hydrothiolation reactions can proceed under a variety … WebSilane SAMs and thiols on gold are the most commonly used types. Most molecules that form SAMs have the general characteristics illustrated in Figure I.2.12.8 . Two processes are particularly important for the formation of SAMs ( Ulman, 1991 ): a moderate-to-strong adsorption of an anchoring chemical group to the surface (typically 30–100 ...
