Abstract
Primary and secondary alkyl amines substitute readily one of the para‐methoxy substituents of tris(2,4,6‐trimethoxyphenyl)methyl carbenium ion. With this rapid process, the preparation of permanently charged positive derivatives of amines, amino acids and small C‐protected peptides is achieved. This is utilized here to facilitate the matrix assisted laser desorption ionization‐time‐of‐flight (MALDI‐TOF) analysis of these compounds. Copyright © 2007 John Wiley & Sons, Ltd.
