Abstract

2-Lithiofuran was added to 2-indanone to yield 2-(2-furyl)indene (4) afterhydrolytic workup. Treatment of 4 with n-butyl-lithium gave 2-(2-furyl)indenyllithium (5). Subsequent reaction of 5 with 0.5 molar equivalents of zirconium tetrachloride in toluene yielded bis[2-(2-furyl)indenyl]zirconium dichloride (6) that was characterized by X-ray diffraction. The homogeneous 6-methylalumoxane Ziegler-Natta catalyst produced elastomeric polypropylene. (C) 2001 Elsevier Science B.V. All rights reserved.
