As is typical for an S N 2 process, benzylic, allylic, and α-carbonylated alkyl halides are excellent reactants. Even though alkyl chlorides are poor alkylating agents ( gem -dichlorides especially so), amines should not be handled in chlorinated solvents such as dichloromethane and dichloroethane, especially at high temperatures, due to the ...
Schotten–Baumann reaction also refers to the conversion of acid chloride to esters. The reaction was first described in 1883 by German chemists Carl Schotten and Eugen Baumann. [1] [2] The name "Schotten–Baumann reaction conditions" often indicate the use of a two-phase solvent system, consisting of water and an organic solvent.
Benzyl chloride, or α-chlorotoluene, is an organic compound with the formula C 6 H 5 CH 2 Cl. This colorless liquid is a reactive organochlorine compound that is a widely used chemical building block .
One method for preparing β-phenethylamine, set forth in J. C. Robinson and H. R. Snyder's Organic Syntheses (published 1955), involves the reduction of benzyl cyanide with hydrogen in liquid ammonia, in the presence of a Raney-Nickel catalyst, at a temperature of 130 °C and a pressure of 13.8 MPa. Alternative syntheses are outlined in the ...
Benzylamine is used as a masked source of ammonia, since after N-alkylation, the benzyl group can be removed by hydrogenolysis: [10] C 6 H 5 CH 2 NH 2 + 2 RBr → C 6 H 5 CH 2 NR 2 + 2 HBr C 6 H 5 CH 2 NR 2 + H 2 → C 6 H 5 CH 3 + R 2 NH. Typically a base is employed in the first step to absorb the HBr (or related acid for other kinds of ...
The benzyl alcohol thus formed is quickly converted to the chloride under the reaction conditions. Mechanism of Blanc chloromethylation Other possibilities for the electrophile include (chloromethyl)oxonium cation (ClH 2 C–OH 2 + ) or chlorocarbenium cation (ClCH 2 + ), which may be formed in the presence of zinc chloride.

Substituted phenethylamines (or simply phenethylamines) are a chemical class of organic compounds that are based upon the phenethylamine structure; [note 1] the class is composed of all the derivative compounds of phenethylamine which can be formed by replacing, or substituting, one or more hydrogen atoms in the phenethylamine core structure with substituents.
(c 6 h 5) 2 ch − + ch 3 ch 2 ch 2 ch 2 br → (c 6 h 5) 2 chch 2 ch 2 ch 2 ch 3 + br − Alkylation of various benzhydryl compounds has been demonstrated using the corresponding alkyl halides, both primary ( benzyl chloride , β-phenylethyl chloride , and n-octyl bromide) and secondary ( benzhydryl chloride , α-phenylethyl chloride , and ...
