Synthesis of Amidoand Diamidophosphites with Polyﬂuoroalkyl Substituents
Bis(polyﬂuoroalkyl) chlorophosphites and polyﬂuoroalkyl dichlorophosphites react easily with secondary amines (-40÷-22°C, 1-3 h, CH2Cl2) in the presence or absence of triethylamine to form the corresponding bis(polyﬂuoroalkyl)diorganylamidophosphites or bis(diorganylamido)polyﬂuoroalkyl phosphites in the yield of up to 74%. Bis(polyﬂuoroalkyl) diorganylamidophosphites were also synthesized from diorganylamidodich lorophosphites and polyﬂuoroalkanols (-25÷-22°C, 2 h, Et3N-CH2Cl2) with a yield of 56-60%.
