[1] Addition of carbon tetrachloride to olefins in the presence of copper complexes with polyfunctional ligands chemically immobilized on the surface of silica / V. V. Smirnov, I. G. Tarkhanova, A. I. Kokorin et al. // Kinetics and Catalysis. — 2005. — Vol. 46, no. 1. — P. 72–76. Homogeneous and heterogeneous catalysts containing copper complexes with amino alcohols and hydroxy amino acids were synthesized. Heterogenized systems were immobilized on the surface of silica by covalent bonding of the hydroxyl groups of ligands to the silanol groups of silica. The resulting complexes were active in the reactions of CCl4 addition to multiple bonds of olefins. In the case of 1-octene, the activity of heterogeneous catalysts was an extremal function of metal concentration on the surface, whereas a symbatic relationship was observed for a chlorinated olefin (allyl chloride). The above effects were explained by the participation of different copper complexes, in particular, of different nuclearity, in reactions with different olefins. [ DOI ]
