Cyclohexylamine is used as an intermediate in synthesis of other organic compounds. It is the precursor to sulfenamide -based reagents used as accelerators for vulcanization. The amine itself is an effective corrosion inhibitor. It has been used as a flushing aid in the printing ink industry. [ 5]
The Curtius rearrangement (or Curtius reaction or Curtius degradation ), first defined by Theodor Curtius in 1885, is the thermal decomposition of an acyl azide to an isocyanate with loss of nitrogen gas. [ 1][ 2] The isocyanate then undergoes attack by a variety of nucleophiles such as water, alcohols and amines, to yield a primary amine ...
mechanism. In organic chemistry, the Ei mechanism ( Elimination Internal/Intramolecular ), also known as a thermal syn elimination or a pericyclic syn elimination, is a special type of elimination reaction in which two vicinal (adjacent) substituents on an alkane framework leave simultaneously via a cyclic transition state to form an alkene in ...
Williamson ether synthesis. The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol ( alkoxide ). This reaction was developed by Alexander Williamson in 1850. [ 2] Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an S N 2 reaction.
The Cook–Heilbron thiazole synthesis highlights the formation of 5-aminothiazoles through the chemical reaction of α-aminonitriles or aminocyanoacetates with dithioacids, carbon disulphide, carbon oxysulfide, or isothiocyanates at room temperature and under mild or aqueous conditions. [ 1][ 2] Variation of substituents at the 2nd and 4th ...
Phenyl group. In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C6H5, and is often represented by the symbol Ph (archaically φ ). The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to ...
An arylcyclohexylamine is composed of a cyclohexylamine unit with an aryl moiety attachment. The aryl group is positioned geminal to the amine. In the simplest cases, the aryl moiety is typically a phenyl ring, sometimes with additional substitution. The amine is usually not primary; secondary amines such as methylamine or ethylamine, or ...
The Peaucellier–Lipkin linkage (or Peaucellier–Lipkin cell, or Peaucellier–Lipkin inversor ), invented in 1864, was the first true planar straight line mechanism – the first planar linkage capable of transforming rotary motion into perfect straight-line motion, and vice versa. It is named after Charles-Nicolas Peaucellier (1832–1913 ...
