Rhodium-containing hypercross-linked polystyrene as a heterogeneous catalyst for the hydroformylation of olefins in supercritical carbon dioxide

A simple procedure for the incorporation of rhodium nanoparticles into a hypercross-linked polystyrene matrix is developed. The prepared heterogeneous catalyst shows high activity in the hydroformylation of olefins in supercritical carbon dioxide, and can be recycled six times without any noticeable decrease in productivity.

New acyclic (π-Allyl)-closo-rhodacarboranes with an agostic CH 3...Rh bonding interaction that operate as unmodified rhodium-based catalysts for alkene hydroformylation

A series of new agostic (CH3...Rh) (π-allyl)-closo- rhodacarboranes (π-allyl = 1,1-dimethylallyl, 1,2-dimethylallyl, 1,1,2-trimethylallyl, 1,2,3-trimethylallyl), stable in the solid state, have been synthesized via one-pot reactions between the K+ salts of the [7-R-8-R′-7,8-nido-C2B9H10]- monoanions (1a, R = R′ = Me; 1b, R,R′ = μ-(o-xylylene); 1c, R,R′ = μ-(CH2)3) and the di-μ-chloro cyclooctene rhodium dimer [(η2-C8H14) 4Rh2(μ-Cl)2] (2) in the presence of a 3-fold excess of the conjugated 1,3-dienes 2-methylbuta-1,3-diene (isoprene, 3), 2,3-dimethylbuta-1,3-diene (4), and 3-methylpenta-1,3-diene (5). The agostic structures of [3-{(1-3-η3)-1,1-dimethylallyl}-1,2-(CH 3)2-3,1,2-closo-RhC2B9H 9] (7a) and [3-{(1-3-η3)-1,1,2-trimethylallyl}-1,2- (CH3)2-3,1,2-closo-RhC2B9H 9] (8a) have been unambiguously confirmed by single-crystal X-ray diffraction studies. Two of these π-allyl complexes prepared were evaluated for their efficacy in hydroformylation of the model alkenes under syngas (CO/H2) using supercritical carbon dioxide (scCO2) as the solvent, and both display excellent conversion and high regioselectivity in the formation of aldehyde products.
