4-Cyano-5,6-dimethylpyridazin-3-(2H)-thione 3b was used as a key intermediate for the synthesis of novel polysubstituted thieno[2,3-c] pyridazines.

Co-doped Ce0.94Ca0.05Sr0.01O1.94 (CCSO) nano particles have been successfully synthesized by an auto-combustion method and were characterized by XRD, TEM and AFM analyses. The catalytic activity of the nano-catalyst is evaluated by the synthesis of substituted pyridazines from substituted benzil and cyano acetylhydrazide, which have great biological and pharmaceutical interest. Thus, a highly economically efficient one-pot solvent free synthesis of pyridazine was developed, which is promoted by the CCSO nano catalyst. The benefits of the reaction are its very short time (2-4 min) and high yields (90-95%). The method offers a highly convergent, inexpensive, and functionality-tolerable procedure for rapid access to important pyridazine compounds in good yields. This journal is

Novel series of thieno[2,3-c]pyridazines and pyrimido[4′,5′:4, 5] thieno-[2,3-c]pyridazines have been synthesized from the readily accessible 4-cyano-5,6-dimethylpyridazin-3(2H)-thione 3b. Copyright Taylor & Francis Inc.
