SYNTHESIS OF 2,3-DIARYL-2,3,4,4а-TETRAHYDRO-5Н-INDENO[1,2-c]PYRIDAZIN-5-ONES

Abstract
The reaction of 1,3-indanedione-derived donor-acceptor cyclopropanes with phenylhydrazine in the presence of catalytic amounts of scandium trifluoromethanesulfonate leads to the formation of indeno[1,2-c]pyridazine derivatives.
