Couplin of organotin reagents Bu3SnAr (Ar = 2- or 3-thienyl, 2- or 3-pyridyl) with ClCOCH2CH2CO2Et in the presence of PdCl(CH2Ph)(PPh3)2 yields beta-ketoesters ArCOCH2CH2CO2Et which were converted with hydrazine hydrate into 6-substituted 4,5-dihydropyridazin-3(2H)-ones, and thence to 3-halogeno-6-substituted pyridazines.The latter also couple under similar conditions with Bu3SnAr to yield 3-heteroarylpyridazines.With catalysts, coupling of ClCOCO2Et and Bu3SnAr proceeds with loss of carbon monoxide giving ArCO2Et, but without catalyst ArCOCO2Et is formed from which the3-heteroarylquinoxalin-3-one is prepared.The reactions of Bu3SnAr with 4-XC6H4Br (X = H,-OMe, -CN, -NO2) are also described.
