Novel Cp2LnX-mediated coupling-cyclization of propargyl bromide: A new construction of the benzene ring skeleton
In the presence of Cp2LnX-HgCl2, the treatment of RC≡CCH2Br with Mg leads to the formation of benzene derivatives C6H4R2-1,2 (R = H, Ph) in moderate yield, which provides a new method for the construction of the benzene ring skeleton.

A zirconocene-coupling route to substituted poly(p- phenylenedienylene)s: Band Gap tuning via conformational control
A series of substituted poly(p-phenylenediyne)s (1a-f) was synthesized by the palladium-catalyzed cross-coupling condensation of terminal dialkynylalkanes with substituted diiodobenzenes. Polymerizations were conducted with 1,4-diiodo-5-hexoxy-2-methoxybe
