Trialkyl phosphites and dialkyl bromomalonates have been reported to react at 0'to give enol phosphates or at 150” to give phosphonomalonates. However, examination of infrared and nmr spectra of trialkyl phosphitedialkyl bromomalonate reaction products has failed to provide any evidence of phosphonomalonate formation. Instead, enol phosphates are produced at both temperatures. Fatty acyl phosphates, which can be prepared from the ...
