With dimethyl and diethyl phosphorisocyanatidites, 4,4,4-trifluoroacetoacetic ester forms substituted 1,4,3-oxazaphospholidines, but with bis(2,2,3,3-tetrafluoropropyl) phosphorisocyanatidite it forms a dimeric product with a diazadiphosphetidine ring containing 5-coordinate phosphoric atoms. IR and phosphorus 31 NMR spectra are analyzed in detail to confirm the structure of these products.
