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

Novel trimethyl-acetyl-octalins mixtures are prepared by a Diels-Alder-type reaction involving methyl vinyl ketone and compounds having the structure ##STR1## wherein one of the two lines denoted by dots represents an additional bond. The novel compounds possess unique and unexpected desirable olfactory properties.
