In organic chemistry, an alkyl group is an alkane missing one hydrogen. [1] The term alkyl is intentionally unspecific to include many possible substitutions. An acyclic alkyl has the general formula of −CnH2n+1. A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −CnH2n−1 ...
Dicarboxylic acid. In organic chemistry, a dicarboxylic acid is an organic compound containing two carboxyl groups (−COOH). The general molecular formula for dicarboxylic acids can be written as HO2C−R−CO2H, where R can be aliphatic or aromatic. In general, dicarboxylic acids show similar chemical behavior and reactivity to monocarboxylic ...
In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C (=O)−OH) [ 1 ] attached to an R-group. The general formula of a carboxylic acid is often written as R−COOH or R−CO2H, sometimes as R−C (O)OH with R referring to an organyl group (e.g., alkyl, alkenyl, aryl), or hydrogen, or other groups.
The reaction begins with the formation of a selenophosphonium salt which reacts with the alcohol to form an oxaphosphonium salt. The aryl selenium anion displaces tributylphosphine oxide forming the alkyl aryl selenide species. The selenide is then treated with excess hydrogen peroxide leading to the selenoxide which eliminates the β-hydrogen ...
In chemistry, an alcohol (from the Arabic word al-kuḥl, الكحل) is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. [2][3] Alcohols range from the simple, like methanol and ethanol, to complex, like sugars and cholesterol. The presence of an OH group strongly modifies ...
Carbamate. In organic chemistry, a carbamate is a category of organic compounds with the general formula R2NC (O)OR and structure >N−C (=O)−O−, which are formally derived from carbamic acid (NH2COOH). The term includes organic compounds (e.g., the ester ethyl carbamate), formally obtained by replacing one or more of the hydrogen atoms by ...
Typical alkylating agents are alkyl halides. Industry often relies on green chemistry methods involving alkylation of amines with alcohols, the byproduct being water. Hydroamination is another green method for N-alkylation. In the Menshutkin reaction, a tertiary amine is converted into a quaternary ammonium salt by reaction with an alkyl halide ...
For the chemical compound, see Acetyl chloride. General chemical structure of an acyl chloride. In organic chemistry, an acyl chloride (or acid chloride) is an organic compound with the functional group −C (=O)Cl. Their formula is usually written R−COCl, where R is a side chain. They are reactive derivatives of carboxylic acids (R−C (=O)OH).
