Bromobenzenes may be carboxylated into carboxylic acids using carbon monoxide.The reaction takes place in a two-phase mixture of p-xylene and water as solvent, in the presence of catalytic PdCl
lic 6 h 4 ch 2 n(ch 3) 2 + e + → 2-ec 6 h 4 ch 2 n(ch 3) 2 Via these reactions, many derivatives are known with the formula 2-X-C 6 H 4 CH 2 N(CH 3 ) 2 (E = SR, PR 2 , etc.). The amine is basic and undergoes quaternization with alkyl halides (e.g. hexyl bromide ) to give quaternary ammonium salts: [ 4 ]
