Spiro is well accessible in ca. 60percent yield by reaction of indene with sodium amide and 1,2-dibromoethane.The suitability of 3 as building block for the synthesis of multi electron ligands is demonstrated by one-pot preparati

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.
