Dimethylbenzylamine is the organic compound with the formula C 6 H 5 CH 2 N(CH 3) 2. The molecule consists of a benzyl group, C 6 H 5 CH 2 , attached to a dimethyl amino functional group . It is a colorless liquid.
Ortho effect is an organic chemistry phenomenon where the presence of a chemical group at the at ortho position or the 1 and 2 position of a phenyl ring, relative to the carboxylic compound changes the chemical properties of the compound.
Benzylamine, also known as phenylmethylamine, is an organic chemical compound with the condensed structural formula C 6 H 5 CH 2 NH 2 (sometimes abbreviated as PhCH 2 NH 2 or BnNH 2).It consists of a benzyl group, C 6 H 5 CH 2, attached to an amine functional group, NH 2.
The Sommelet–Hauser rearrangement (named after M. Sommelet [1] and Charles R. Hauser [2]) is a rearrangement reaction of certain benzyl quaternary ammonium salts. [3] [4] The reagent is sodium amide or another alkali metal amide and the reaction product a N,N-dialkylbenzylamine with a new alkyl group in the aromatic ortho position.
There are 2 ortho positions, 2 meta positions and 1 para position on benzene when a group is attached to it. When a group is an ortho / para director with ortho and para positions reacting with the same partial rate factor, we would expect twice as much ortho product as para product due to this statistical effect.
[6] [7] The reagent is sodium amide or another alkali metal amide and the reaction product a N,N-dialkylbenzylamine with a new alkyl group in the aromatic ortho position. For example, benzyltrimethylammonium iodide, [(C 6 H 5 CH 2)N(CH 3) 3]I, rearranges in the presence of sodium amide to yield the o-methyl derivative of N,N-dimethylbenzylamine ...
According to calculations, ortho-diethynylbenzene dianion is the strongest superbase and has a proton affinity of 1,843.987 kJ/mol (440.723 kcal/mol). [1] The meta isomer is the second-strongest, and the para isomer is the third. All three are readily able to accept any proton to its ethynyl tails, from almost any compound.
The Dakin oxidation. The Dakin oxidation (or Dakin reaction) is an organic redox reaction in which an ortho- or para-hydroxylated phenyl aldehyde (2-hydroxybenzaldehyde or 4-hydroxybenzaldehyde) or ketone reacts with hydrogen peroxide (H 2 O 2) in base to form a benzenediol and a carboxylate.
