Description

Application

Isopropyl p-toluenesulfonate can be used as a reactant:

• For the alkylation of amines in the presence of triethylamine.
• For the O-alkylation of cyclic thiohydroxamic acids in the presence of tetrabutylammonium hydroxide.
• To synthesize 3-methyl-2-phenyl-1-butanol by reacting with styrene in the presence of bromo(2-cyclohexylethyl)magnesium and zirconocene dichloride.

Isopropyl p-toluenesulfonate can be used:

• as a thermal acid generator that synthesizes inherently stretchable p-conjugated polymer
• as a catalyst for the deprotection of PBHEMA [Poly(2-(tert-butoxycarbonyloxy)ethyl methacrylate)] on heating
