Rhodium carbonyl, Rh4

Interaction of the dibenzylideneacetone complex of palladium with a high surface area carbon gave a supported complex which on heating produced a Pd/C catalyst having a uniform distribution of palladium metal particle sizes. The rhodium carbonyls, Rh4(CO) 2 and Rh6(CO) 6, were adsorbed on silica to give... 

Rhodium carbonyl, Rh4(CO)I2, catalyzes the cyclocarbonylation of acetylenes with benzene to give indenones. For example 2,3-diphenyl -indenone is obtained from diphenyl acetylene and benzene in 10% yield, corresponding to a catalytic turnover of 11 (220°C, 25 bar, 7 hr)... 

Rhodium carbonyl, Rh4(CO)ig, catalyses the cross-hydrocarbonylation of acetylenes and ethylene under pressure to give ap-unsaturated ethyl ketones [equation (28)]. The reaction shows high regioselectivity for terminal alkynes, giving the transAsomex,...
