Pentacarbonyliron-promoted conversion of 3a,7a-dihydroindenones into indanones
Abstract
Reactions of 3a-7a-dihydroindenones or 3a,4,7,7a-tetrahydro-4,7-methanoindene-1,8-diones with Fe(CO)5 afford indanones as the sole products. No corresponding diene–Fe(CO)3 complexes have been detected. The mechanisms for these reactions are established on the basis of deuterium-labelling experiments.
