The Michael Addition Reaction (and Conjugate Addition) The Michael reaction (sometimes “Michael Addition”) is the addition of an enolate to an electrophilic alkene, such as an alpha-beta unsaturated ketone, nitrile, or ester The primary driving force is formation of a C-C (single) bond (80...
Thekey attribute of the thiol-Michael addition reaction that makesit a prized tool in materials science is its modular "click"nature, which allows for the implementation of this highly efficient,"green" reaction in applications that vary from smallmolecule synthesis to in situ polymer modifications ...
