Ring-opening polymerization water-soluble derivatives

Ruthenium-catalysed Ring-Opening Metathesis Polymerization (ROMP) 29 526 529 (Equation 10) and Pd(tppms)3-catalysed synthesis of water soluble poly-(p-phenylene) derivatives (Equation ll).530 The latter is a special example of a Suzuki coupling (see earlier). 

Grubbs and co-workers reported the ring-opening metathesis polymerization (ROMP) of norbornene derivatives in water using Ru(H20)6(ts)2 as the catalyst [127, 128]. More recently, these authors have described the first example of a homogeneous living polymerization in water using a water-soluble ruthenium carbene [Eq. (24)] [129].
