The ethoxycarbonylimme of perfluoroacetone reacts with phosphorus pen-tachlonde under mild condtions This reaction is a convenient synthesis of a-chlo-rohexafluoropropyl isocyanate [73] (equauon 60). 

Isomeric products (75) and (76) are obtained from the reaction of perfluoroacetone with dialkyl phosphites. " The relative proportions of the isomeric mixture depend on the alkyl group in the phosphite and the results are explained in terms of the polarity of the P-H bond and hence its direction of addition to the carbonyl group. Presumably, the balance in these cases is very finely adjusted, although these reactions are possibly more complicated than the results suggest.
