Abstract
Thallium cyclopentadiene (Cp) salts are important precursors for the synthesis of a variety of compounds having materials and commercial applications. The synthesis of 5,6-fused ring thallium Cp pyridazines 2a–d from previously reported 5,6-fused ring pyridazines is described herein. This route was quite general, and features an efficient and convenient two-step synthesis of a series of TlCp salts in a THF solution of thallium ethoxide. Full characterization of newly formed TlCp salts 3a–d are reported.
