Nucleosides and Nucleotides. Part 19. On Detritylation with Zinc Bromide in Oligonucleotide Synthesis

Abstract
Zinc bromide has been shown by several groups of workers to be a useful reagent in the removal of trityl protecting groups from nucleotides. An attempt is made here to establish optimum conditions for the reaction, a strange observation is reported, and a novel workup via a soluble, lipophilic zinc complex is described.
