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。

Electrocatalytic addition of perfluoroalkyl iodides to 3-hydroxy-3-alkylbut -1-ynes, followed by dehydroiodination and thermal cleavage in basic medium, leads to an easy and efficient preparation of (perfluoroalkyl)alkynes.

Under the conditions of the Rupereaction hydration of the triple bond of the perfluorobutylalkynols n-C4F9CCCR(Me)OH occur yielding the ketone n-C4F9CH2COCR(Me)OH; this ketone undergoes intramolecular reaction providing an interesting route to 5-n-perfluoropropylfuran-3(2H)-ones.
