Formation of Metal Clusters by the Ship-in-a-Bottle Method

Formation of Metal Clusters by the Ship-in-a-Bottle Method 

Bimetal carbonyl clusters of RhFe were synthesized inside supercages of NaY by reaction of Rh4(CO)i2 with [HFe3(CO)n] /NaY in vacuo at 100°C (262). The pale red-brown RhFe carbonyl clusters in NaY catalyze the hy-droformylation of ethylene and propylene with high selectivity to alcohols, whereas this selectivity is lower for supported pale grey Rh carbonyls and pink-purple Fe carbonyls. With Pd phosphine carbonyl clusters in NaY the hydroformylation of propene displays high selectivity for C7 ketones, which are formed by reaction of propene with the primary hydroformylation product, C4 aldehyde (263).
