WebIn organosulfur chemistry, the thiol-ene reaction (also alkene hydrothiolation) is an organic reaction between a thiol (R−SH) and an alkene (R 2 C=CR 2) to form a thioether (R−S−R’). This reaction was first reported in 1905, but it gained prominence in the late 1990s and early 2000s for its feasibility and wide range of applications. WebThis work describes a study into thiol–ene based Michael addition reactions. Different catalysts, primary and tertiary amines and phosphines, were investigated for the reaction of a range of thiols with dimers and oligomers of some (meth)acrylates. Primary and tertiary amines are efficient catalysts for the Polymer Chemistry Lectureship Winners RACI100: …
