Combinedexperimental and computational studies showthat the ironcomplex exhibits adual catalytic role in that the non-innocentcyclopentadienone ligand acts as proton shuttle by initialhydrogen abstraction from the alcohol and by facilitatingprotonation and deprotonation events in the isomerization anddemetalation steps.Molecular orbital analysis provides insightinto the unexpected and selective formation of the 3,4-dihydro-2H-pyran. | URI: | http://hdl.handle.net/10553/74930 | ISSN: | 1433-7851 | DOI: | 10.1002/anie.201708240 | Fuente: | Angewandte Chemie - International Edition [ISSN 1433-7851], v. 56, p.14863 –14867 |
