Fluorenone BACKGROUND
Fluorenone invention is in the fields of neurology and pharmacology and relates to drugs that can minimize brain injury. from various causes such as traumatic head injury or crises such as stroke, cardiac arrest or asphyxiation.
The compounds disclosed herein belong to a class of compounds first discovered in the 1970’s recognized as potentially useful in reducing brain damage. A great deal of time, effort and expense has gone into these drugs, and they have been extensively patented and studied by one of the world’s largest pharmaceutical companies, Merck & Company, Inc.
Importance
Fluorenones are important constituents in material, medical and chemical sciences with potential applications in various domains. The key factors responsible for the diverse usage of fluorenones in material sciences are their intriguing and tunable photo, as well as physico-chemical properties. Besides this, the presence of conjugated polynes in the fluorenones makes them molecules of interest in material sciences.
Fluorenones show various biological activities like antibiotics, anticancer, antiviral, and neuromodulatory, etc. Organic chemists are developing various protocols for the synthesis of fluorenones. Despite several protocols developed for their synthesis since 1931, there is no review covering their entire synthetic protocols. This review includes several classical and novel synthetic approaches for the synthesis of fluorenones.
we delineated the mechanism synthesized.
Derivatives
The optoelectronic devices due to their high thermal stability, ease of preparation. Hence a much better match between the solar radiation and absorption.
It leading in turn to a much better device efficiency as compared to fluorene-derived counterparts. However, organic dyes containing the fluorenone moiety are still not very well studied to date.
Solubility of Fluorenone
The next thing Tom’s professor discusses is the solubility of fluorenone. When we talk about the solubility of a compound, we refer to whether or not it will form a solution with a given solvent, in other words, will it dissolve. If it does, we say that the compound is soluble. If it doesn’t, it is insoluble.
Fluorenone is soluble in a wide range of organic solvents (solvents that are carbon-hydrogen based) including things like chloroform, methanol, ethanol, dichloromethane, and acetonitrile.
An important thing to realize however, is that fluorenone is NOT soluble in water. This is actually the case for a lot of organic compounds. The reason will become more apparent when we talk about its polarity in the next section.
Stability
The excellent stability, electron-donating ability and inhibition of aggregation. Due to a non-planar molecular configuration of triphenylamine-based sensitizers have made them a prospective chromophore for DSSC applications. As a continuation of our efforts to develop functional materials suitable for DSSCs four new fluorenone-functionalized organic photosensitizers .F1–F4 of the type D-A-π-A (D = donor, A = acceptor) were designed and synthesized here with triarylamine or fluorene. unit as the electron donor, an additional fluorenone unit as a mild electron-withdrawing linkage and a cyanoacrylic acid moiety as the electron-withdrawing and anchoring group.
Structure of Fluorenone
Fluorenone is an aromatic compound that contains a five-memberedring with a carbonyl group attached and two benzene rings fused on either side. Let’s break that down a bit.
‘Aromatic’ means that the compound contains an alternating network. of double and single bonds all the way around each benzene ring. We could say that the five-membered ring has a benzene ring ‘fused’ to each side of it.

Capric acid
It also known as decanoic acid or decylic acid, is a saturated fatty acid, medium chain fatty acid (MCFA) and carboxylic acid. Its formula is CH3(CH2)8COOH. Salts and esters of decanoic acid are called caprates or decanoates. The term capric acid derives from the Latin “caper/capra” (goat) because the sweaty, unpleasant odor of the compound is reminiscent of goats.
Appearance
Capric acid occurs naturally in coconut oil (ca. 10%) and palm kernel oil (ca. 4%), but is otherwise uncommon in typical seed oils.[10] It is found in the milk of various mammals and to a lesser extent in other animal fats. Two other acids are named after goats: caproic acid (a C6:0 fatty acid) and caprylic acid (a C8:0 fatty acid). Together with capric acid, these make up 15% of goat’s milk fat.
Production
Capric acid can be produced by oxidizing the primary alcohol decanol using chromium trioxide (CrO3) as the oxidizing agent under acidic conditions. Neutralization of capric acid or saponification of its triglyceride esters with sodium hydroxide gives sodium caprate, CH3(CH2)8CO−2Na+. This salt is part of some types of soap.
Uses
Capric acid is used in the manufacture of esters for artificial fruit flavors and fragrances. It is also used as an intermediate in chemical syntheses. It is used in organic synthesis and industrially in the manufacture of perfumes, lubricants, fats, rubber, dyes, plastics, food additives and medicines.
