Rh(I) - Cu(II) Catalyzed Oxidation of 1-Hexene by o2 using Immobilized, Site-Separated Organosulfide Complexes,
Abstract
Silica gel bound organosulfide (SG-SH) was reacted with Rh(CO)2SnBF4 (I) to produce (mu-sg-s)2Rh2(CO)4(II) or SG-SRh(CO)2Sn(III). III was obtained from SG-SH sample processing site-separated organosulfide groups, while II require proximate sulfide groups. III is the first example of a monomeric organosulfide transition metal carbonyl complex which is stable in the absence of additional, non-carbonyl ligands. Both the Rh(I) and Cu(II) species previously reported to be necessary for the O2 oxidation of l-hexene to 2-hexanone were bound to the SG-SH support, and found to be an effective catalytic system for this reaction. The monomeric III was much more active than the dimeric II. Increased lifetimes were observed for the SG-SH bound catalysts, relative to homogeneous analogues.
