摘要:
The phosphinic acid chlorides 6 and 9 react in good yields with N,N-dimethylaminoethanol to the corresponding esters 3 and 10. Reaction of the phenylphosphonous acid esters 1 and 2 with arylbromides, heteroarylbromides and carboxylic acid chlorides give esters of unsymmetrical phosphinic acids. Similarly, cyanphenylphosphinic acid ethylester reacts with aliphatic amines to phosphonic acid esterchlorides.
