Abstract
The reaction of tetrabutyltin with an alumina-containing inorganic oxide su ch as alumina, silica-alumina or boria-alumina, gives active catalysts for olefin metathesis. Infrared results obtained with tin-modified gamma-alumin a and boria-alumina suggest that the active sites arise from an interaction between (n-Bu)(4)Sn and a coordinatively unsaturated Al site, which is cre ated when bridging OH groups react with the tetraalkyltin compound.
