A Diels-Alder Reaction History and Application: The 1950 Nobel prize in chemistry was awarded to Otto Paul Hermann Diels and Kurt Alder for their breakthrough work on the discovery and development of [4 + 2] cycloaddition reactions i. This set of reactions are enormously useful in the synthesis of six membered rings in a single stepii. These are used in many pharmaceutical applications. Tamiflu® is a drug which

Introduction An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. Essential oils are also known as volatile oils‚ ethereal oils or aetherolea‚ or simply as the "oil of" the plant from which they were extracted‚ such as oil of clove. Volatile oils are the odorous and volatile products of various plant and animal species. As they have a tendency to undergo evaporation on being exposed to the air even at an ambient temperature‚ they are invariably termed

Identification Using Infrared Spectroscopy Aim: To identify the functional groups in organic compounds using infrared spectra. APPARATUS AND REAGENTS: Nicolet 380FTIR‚ HATR Accessory (liquid crystal plates) Reagents ( Methanol‚ Benzene and Cyclohexane‚ Cyclohexene) THEORY: An important tool of the organic chemist is Infrared Spectroscopy‚ or "IR". IR spectra are acquired on a special instrument‚ called an IR spectrometer. IR is used to gather information about compound ’s structure‚ assess its purity‚ and

Paul Hermann Diels and Kurt Alder first documented this type of reaction‚ hence the name Diels-Alder reactions. Their reaction is one of the more useful reactions done in chemistry because it does not require very much energy in order to make the cyclohexene ring and the result can create four stereo centers‚ making it compatible for a variety of functional groups which still has double bonds in the products.

Organic Chemistry - Introduction 1 2812 Basic definitions for organic chemistry Scope Organic chemistry is a vast subject so it is easier to split it into small sections for study. This is usually done by studying compounds which behave in a similar way because they have a particular atom‚ or group of atoms‚ (FUNCTIONAL GROUP) in their structure. Catenation The ability to form bonds between atoms of the same element. Carbon catenates to form chains and rings‚ with single‚ double

and serious environmental problems [4]. Research effort has thus been concentrated to search for an economically viable‚ practical (single stage‚ without high amount of recycle) process avoiding use of nitric acid. Recently‚ direct oxidation of cyclohexene to adipic acid with 30% hydrogen peroxide (H2O2) over Na2WO2 and [CH3(n-C8H17)3N]HSO4 as a phase-transfer catalyst (PTC) has been reported (see Figure
