摘要：

The reaction of 2 equiv of LiC5Me4R (R = H, Pr-i, Bu-n) with PbCl2 affords the Pb(C5Me4R)(2) metal-locenes in good yields. Pb((C5Me4Pr)-Pr-i)2 and Pb((C5Me4Bu)-Bu-n)(2) were isolated as red oils, while Pb(C5Me4H)(2) was isolated as an orange solid whose X-ray crystal structure reveals a bent-metallocene structure which has a 139.7 degrees (ring celitroid)-Pb-(ring centroid) angle.
