4-Methylbenzyltrimethylammonium hydroxide is a quaternary ammonium compound with the formula C₁₁H₁₈N⁺OH⁻. It can be synthesized by reacting 4-methylbenzyl bromide with triethylamine, followed by stirring with silver oxide in water.^[1]

Reactions

When heated with phenothiazine in toluene, it undergoes Hofmann elimination to form [2.2]Paracyclophane.^[1]

Paracycloheterophanes can be obtained by heating it with other quaternary ammonium hydroxides (e.g. with (5-methyl-2-thienylmethyl)trimethylammonium hydroxide to form [2.2]paracyclo(2,5)thiophenophane).^[2]
