Abstract
(C5Me4H)SiMe2Cl reacts with (THF)KCH 2CH=CHCH=CH2 to form (C5 Me4H)SiMe2(CH2CH=CHCH=CH2) (1). Compound 1 reacts with KH and n-BuLi to make M(C5 Me4)SiMe2(CH2CH=CHCH=CH 2), M=K, 2; Li, 3, respectively. Carbon-silicon cleavage occurs when 1 reacts with K to form (C5Me4H)K, which crystallizes from dimethoxyethane as [(C5Me4 H)K(DME)]x. This potassium salt has an extended structure which generates bent metallocene (C5Me4H) 2K(DME) sub-structures which have 133.9° ring centroid-K-ring centroid angles. Compound 1 reacts with TiCl4 to make (C5Me4H)TiCl3 (5), which has a piano stool structure. © 2003 Elsevier B.V. All rights reserved.
