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 identical to 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.
