2,2,4,4-Tetramethyl-3-t-butyl-pentane-3-ol or tri-tert-butylcarbinol is an organic compound with formula C 13 H 28 O, ((H 3 C) 3 C) 3 COH, or t Bu 3 COH. [1] It is an alcohol that can be viewed as a structural analog of a tridecane isomer ( 2,2,4,4-tetramethyl-3- t -butylpentane ) where the central hydrogen has been replaced by a hydroxyl group ...
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
Its sodium salt can be prepared from the chloride: [6] (C 6 H 5) 3 CCl + 2 Na → (C 6 H 5) 3 CNa + NaCl. The use of tritylsodium as a strong, non-nucleophilic base has been eclipsed by the popularization of butyllithium and related strong bases. The unmodified anion is red, and can be used as an indicator in acid–base titrations. Derived ...
Common reaction conditions include use of sodium or potassium alkoxide as base in hexane or tetrahydrofuran solvents, at temperatures ranging between 200–400 °C. A hydrolysis step is also required in the synthesis. The Madelung synthesis is important because it is one of few known reactions that produce indoles from a base-catalyzed thermal ...
[2] [3] [4] The aldol reaction is paradigmatic in organic chemistry and one of the most common means of forming carbon–carbon bonds in organic chemistry . [ 5 ] [ 6 ] [ 7 ] It lends its name to the family of aldol reactions and similar techniques analyze a whole family of carbonyl α-substitution reactions , as well as the diketone ...
1,2,3,4,5-Pentakis(4-butylphenyl)-1,3-cyclopentadiene is an organochemical compound from the diene group and a cyclopentadiene derivative. The anion of this compound is used as a sterically demanding ligand, often abbreviated as Cp [BIG] , in the organometallic chemistry of sandwich compounds .
The reaction is much less efficient in homogeneous systems such as dichloromethane, toluene and acetonitrile or even the solvent free reaction or even the water reaction but now at 50°C. The on water effect is also studied in cycloadditions of the type: [6] In this reaction the alkyne methyl 2-octynoate reacts with triphenylphosphine to an ...
The Peterson olefination (also called the Peterson reaction) is the chemical reaction of α-silyl carbanions (1 in diagram below) with ketones (or aldehydes) to form a β-hydroxysilane (2) which eliminates to form alkenes (3).
