1-(2-Hydroxy-4,5-dimethoxyphenyl)ethanone

Abstract

The mol­ecular structure of the title compound, C10H12O4, contains an intra­molecular hydrogen bond between the phenol and acetyl substituents. In the crystal, C—H⋯π inter­actions act between the mol­ecules in a cyclic manner to stabilize stacks of mol­ecules along the b axis. Several C—H⋯O inter­actions are present between the stacks.

Cyclic Voltammetric Study of 2‐Hydroxybenzophenone (HBP) Derivatives and the Correspondent Change in the Orbital Energy Levels in Different Solvents

“…The enol form has been identified to be the only one minimum in the ground state while the chelated keto form identified to be the minimum in the excited state [6,7]. Available solid state crystal structures of HBP and related ligands are all of the chelated enol form [8][9][10][11][12][13].…”

Chromenone‐Fused Pyrrolizines and Pyrrolizine Analogues of Lamellarins: Expanding the Lamellarin Family

“…We have previously reported the synthesis of 17 , [18] while the requisite halides 18 (X=Br) were readily prepared by bromination of the corresponding acetophenones 19 (Scheme 3). The simple o ‐hydroxy acetophenone 19 a , our model for subsequent investigations, is commercially available, while we have previously reported the synthesis and characterisation of the 3,4‐dimethoxy analogue 19 b , [22] which contains substituents more typical of lamellarins. Bromination of 19 a with copper(II) bromide in chloroform‐ethyl acetate by a published method [23] gave the desired bromide 20 a in greater than 90 % yield, while application of the same method to 19 b afforded 20 b in 84 % yield after recrystallisation.…”
