Abstract: Abstract The reaction between Si-containing alkynes and bis (1,3,5-cycloheptatriene-7-yl)alkanes in the presence of the two-component catalyst Ti(acac) 2 Cl 2 -Et 2 AlCl, led to the selective formation of mono- and bis -adducts – {9-[4-(2,4,6-cycloheptatrienyl)alkyl]-8-alkyl(phenyl)bicyclo[4.2.1]nona-2,4,7-triene-7-yl}(trimethyl)silanes… read more here.
