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.

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 ...
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 ...
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 ...

(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 ...
