in toluene a soln. of CpTi(C3H5)2 in toluene was stirred for 2 h at 90°C under vac. in a closed vessel; 0.49 equiv of CH2=CH(CH2)2CH=CH2 per Ti atom was formed; mixt. was cooled in liq. N2 to trap all the products and analyzed by GLC;

hydrogenchloride; carbon monoxide in not given byproducts: propene, 1,5-hexadiene; CpTi(C3H5)2 was treated with CO (1 bar) at ambient conditions (t1/2 1.5min, 24°C, 1.5 equiv of CO per Ti atom was consumed), resulting species (not identified, the absence of CO ligand was shown) was treatedwith HCl/ether;
