Phenyl phosphorodichloridate, 97%

Description

CAS: 770-12-7 | C6H5Cl2O2P | 210.978 g/mol

Reagent for preparation of phosphate diesters.Phenyl phosphorodichloridate is used in the preparation of symmetrical phosphate diesters. It is used as a phosphorylating agent for alcohols and amines. It is also involved in the preparation of phenylphosphoro di-(1-imidazolidate) and 2-phenyl-bis-triazoloylphosphate, which is used in peptide synthesis. It plays a vital role in the Pfitzner-Moffatt oxidation which involves oxidation of alcohols to the corresponding aldehydes and ketones. Furthermore, it is utilized in Beckmann rearrangement for the preparation of N-phenylacetamide from acetophenone oxime.
