A new Rh-catalyst system has been developed for the [4+2] and [5+2] cycloadditionreactions. This new system shows high reactivity at room temperature and the Rh-center bears tunable phosphine ligands. Up to 1000 turnovers have been obtained for the [4+2] cycloadditionreaction at room temperature.

blocks with a palladium or platinum precursor. These spheres can be functionalized on the inside with a gold(I) chloride complex leading to a high local concentration of gold(I) complexes. The high local concentration makes the neutral gold species an active catalyst. Furthermore, the platinum‐gold spheres can be post‐modified with a silver(I) salt to form cationic gold(I) catalysts. The platinum assemblies
A rhodium catalyst is reported that catalyzes the cycloisomerization of dieneynes and trienes. This cycloisomerization reaction, formally the equivalent of an unactivated Diels-Alder reaction, proceeds at room temperature with [Rh(DIPHOS)(CH2Cl2)(2)] SbF6 as the catalyst.
