PQS: A New Platform for Micellar Catalysis. RCM Reactions in Water, with Catalyst Recycling

The first “designer” surfactant containing a covalently bound ruthenium catalyst is reported. This species dissolves freely in water, forming nanomicelles in which ring-closing metathesis reactions on water-insoluble dienic substrates can occur in pure water at room temperature. It can also be recycled continuously without reaction workup.
