Usage

General Description

5,7-DIMETHYL-1-INDANONE, also known as dimethylindanone, is a chemical compound with the molecular formula C11H14O. It is a colorless to pale yellow liquid with a sweet, woody odor and is commonly used as a fragrance and flavoring agent in the perfume and food industries. It is also used as an intermediate in the synthesis of pharmaceuticals and other chemicals. 5,7-DIMETHYL-1-INDANONE is known for its high solubility in alcohol and acetone and its low solubility in water. It is considered to be relatively stable under normal conditions and has low acute toxicity. However, it should be handled with caution as prolonged exposure to the compound may cause skin irritation and respiratory issues.

Unique solvent effect on photochemistry of ortho-alkylphenacyl benzoates

Photolysis of 2,4,6-trialkylphenacyl benzoates gives not only the corresponding indanones and benzoic acid, but also the corresponding benzocyclobutenols (CBs), which are also detected in the photolysis of mono-alkylphenacyl benzoates for the first time.

Chromic Acid Oxidation of Indans and Tetralins to 1-Inadanones and 1-Tetralones Using Jones and Other Cr(VI) Reagents

The Jones chromic acid oxidation, ordinarily used for converting secondary alcohols to ketones, has been successfully extended to the oxidation of indans and tetralins to 1-indanones and 1-tetralones, respectively.A sixfold excess of the reagent was commonly used to ensure complete oxidation of starting material.Addition of anhydrous magnesium sulfate or oven-dried silica gel provided a yield increase of 15-20percent. 2,2'-Bipyridinium chlorochromate was also used and found to be effective in all cases, but this reagent requires a longer reaction time and a 16-fold excess.A comparison between these two reagents and CrO3 in acetic acid was made.The Jones reagent being least selective, gives the highest yield of sterically hindered monoketone from 1,2,3,4,5,6,7,8-octahydrophenanthrene.
