Methylation of 5-Aldehydo-6-arylpyridazin-3(2H)-ones via Reaction with Dimethyl and Pentamethyl Cuprates

Me5Cu3Li2 in ether or ether-pentane mixtures, converts the title compounds efficiently into the corresponding 4-methyl derivatives (5) via conjugate methylation of either α,β-unsaturated aldehyde or N=C-C=C system, together with ca. 20percent of 1,2 adduc
