The Ti(IV) complexes 1b, 2b, and 6 have been synthesized from new multi-electron ligands. 2b, after reduction with Et2AlCl, dimerizes isoprene mainly to 8c and trimerizes butadiene mainly to ttt-CDT. Ti(IV) compounds of the macrocyclic ligands 7a-c exhibit the same catalytic properties after reduction with Et2AlCl.
Ti(IV)配合物1b,2b和6是由新的多电子配体合成的。用Et 2 AlCl还原后的2b,主要将异戊二烯二聚为8c,将丁二烯主要三聚为ttt-CDT。用Et 2 AlCl还原后,大环配体7a-c的Ti(IV)化合物显示出相同的催化性能。
