Description

General description

2-Chlorotrityl chloride resin is an extremely versatile, acid-labile resin for the solid phase immobilization of carboxylic acids ^{[1,2,3,4,5,6, 20]}, alcohols ^{[7,8,9, 20]}, phenols ^{[10,11,12,13, 20]} and amines ^{[14,15,16,17,18,19,20]}, imidazoles ^[20] and hydroxylamines ^[21,22]. Release of these functionalities is generally achieved using 1-50% TFA in DCM containing 5% TIS, although carboxylic acids can also be cleaved from this support with AcOH/TFE/DCM ^{[1,2,3,4,5,6]},0.5% TFA in DCM, or HFIP in DCM ^[23]_.
