The Prop-2-ynyldiethylphosphites n-C4F9–CC-CR1R2OP(OEt)2 are obtained from the reaction of the corresponding prop-2-ynyl alcohols with diethyl chlorophosphite; the rearrangement of these phosphates into α-perfluorobutylallenic phosphonates is found to depend on the nature of the substituent R1 and R2, and an unexpected HF elimination is found for R1= H, R2= Me.
丙-2-炔基二乙基亚磷酸酯nC 4 F 9 –C C-CR 1 R 2 OP(OEt)2是由相应的丙-2-炔基醇与亚磷酸二乙酯反应制得的。发现这些磷酸盐重新排列为α-全氟丁基亚烷基膦酸酯取决于取代基R 1和R 2的性质,并且对于R 1 = H,R 2 = Me ,发现了意外的HF消除。
