The distinctive fluorine effects on “on-water” chemistry have remained less explored. In this work, an “on-water” reaction of β-trifluoromethylated enones with phosphine oxides was developed for the preparation of highly functionalized gem-difluorodienes with excellent Z-selectivity. The reaction occurred through a well-designed tandem phospha-Brook rearrangement and defluorination sequence under

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.
