Hydroboration of Bis(alkenylcyclopentadienyl)zirconium Dichlorides
Erker, Gerhard,Aul, Rainer
, p. 1301 - 1310 (2007/10/02)
The reaction of allylcyclopentadienyllithium with 0.5 molar equivalents of MCl4(thf)2 (M = Zr, Hf) furnished the (η5-C5H4CH2CH=CH2)2MCl2 complexes 3a (Zr) and 3b (Hf), which cleanly added 9-borabicyclononane (9-BBN) to form 5/sup
