Synthesis of Amido- and Diamidophosphites with Polyfluoroalkyl Substituents
摘要:
Bis(polyfluoroalkyl) chlorophosphites and polyfluoroalkyl dichlorophosphites react easily with secondary amines (from -40 to -22 degrees 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 diorganylamidodichlorophosphites and polyfluoroalkanols (-25 to -22 degrees C, 2 h, Et3N-CH2Cl2) with a yield of 56-60%.
