From (IV), chlorosulphonic acid (V) and benzene sulphonic acid (VI) are obtained by the replacement of H by Cl and C6H5 respectively Arguing along similar lines, (VIII) is phosphonic acid and (IX) is fluorophosphonic acid, hence (I) is diethyl chlorophosphonate. Th ... 

Ester chlorides or the readily obtainable chlorophosphonate [84] were used for the synthesis of compounds 154. Hydrolysis of the compound with a twofold excess of water in the presence of hydrochloric acid in DMF solution led to indolylphosphinatoacetaldehydes 155 [151], identified in the form of 2,4-dinitrophenylhydrazones 156 ...
