摘要
9-Hydroxyphenalenone is a planar multicyclic beta-keto-enol that demonstrates C-2v symmetry on the NMR timescale. Off-axis substitution breaks the molecular symmetry and results in tautomers. H-1 and C-13 NMR assignments were made for 9-hydroxyphenalenone and three methyl derivatives, and the solution-phase tautomers were determined. Copyright (c) 2005 John Wiley & Sons, Ltd.
