Abstract
Fused isoxazoles underwent reductive ring-opening in the presence of m olybdenum hexacarbonyl to give the corresponding beta-disubstituted co mpounds. 6-Trimethyl-6,7-dihydro-1,2-benzisoxazol-4(5H)-one oxime unde rwent reductive ring-opening in the presence of molybdenum hexacarbony l to give 3,6,6-trimethyl-6,7-dihydro-1H-indazol-4(5H)-one. A mechanis m is proposed.
