• 論文の詳細を見る

• Various 3-alkynylpyridazines have been prepared by cross-coupling of 3-halopyridazines and monosubstituted acetylenes in Et_2NH with Pd (PPh_3)_2Cl_2-CuI as a catalyst. Though the alkynylation of 3-chloropyridazine 1-oxides afforded 3-alkynylpyridazine 1-oxides, attempts to obtain 3-chloropyridazine 2-oxides were unsuccessful. N-Oxidation of 3-alkynylpyridazines with m-chloroperbenzoic acid yielded their 1-oxides exclusively
