A new water-soluble rhodium catalyst is reported along with its
ability to effect [5+2] cycloaddition
reactions in water. This water-soluble catalyst is recyclable, is
readily separated from the organic product, and allows one to avoid
or minimize the use of organic solvents, the major waste stream
of most organic reactions.
