ABSTRACT:
There is provided a process for the addition of a nucleophile across an electron poor carbon-carbon double bond (a Michael addition) comprising contacting in a solvent: i) a nucleophile; ii) a compound comprising an electron poor double bond; and iii) a catalyst comprising a soluble polymer and a polyamino acid.
