ALKYLATION OF 1-THIOXO-2-PHENYL-4-ARYL-1,2-DIHYDROPHTHALAZINES BY TRIETHYLOXONIUM TETRAFLUOROBORATE
1-Thioxo-2-phenyl-4-aryl-1,2-dihydrophthalazines are alkylated by triethyloxonium tetrafluoroborate exclusively at the thiocarbonyl group with the formation of the salts of heteroaromatic ions.Hydrolysis of the latters lead to 1-oxo-2-phenyl-4-aryl-1,2-di
