and developments during the previous decade are enabling metathesis in aqueous solvents for the manipulation of biomolecules. Indeed in 1988, Grubbs and Novak reported that not only ruthenium was an interesting candidate for olefin metathesis, the number of applications of olefin metathesis in water has dramatically increased. The field of metathesis is continuously growing and scientists seek new opportunities to exploit this powerful CC doublebondforming reaction in different fields of research.
