CAN 134:168789 AN 2000:887031 CAPLUS AbstractA review with 55 refs. that reports the synthesis and characterization of dendrimer -encapsulated metal nanoparticles and their applications to catalysis. These materials are prepd. by sequestering metal ions within dendrimers followed by chem. redn. to

Intradendrimer hydrogenation and carbon-carbon coupling reactions in water, org. solvents, biphasic fluorous/org. solvents, and supercrit. CO2 are
