摘要

In this contribution we report on fluorotrimethyl(Z)-pentafluoropropen- 1-ylphosphorane as a phosphorus based fluorinating reagent. Its solid state structure can be described as a trigonal bipyramid featuring elongated axial bonds due to the formation of a 3-center 4- electron bond. Abstraction of the fluoride ion leads to a shortening of the axial P-C bond. Thus the title compound can be utilized for substitution of bromine with fluorine and for the transfer of fluoride ions onto electrophilic compounds. Reaction with Sn(C_2F_5)_2Br_2 afforded salt P(CH_3)_3(C_3F_5)_2Sn(C_2F_5)_2F_4. When fluorotrimethyl(Z)-pentafluoropropen- 1-ylphosphorane was treated with P(C_2F_5)_2F the primarily produced anion is sufficiently nucleophilic to attack the propenyl group of the cation in β-position to the phosphorus atom to yield zwitterionic Me_3PCF=C(CF_3)-PF_3(C_2F_5)_2.
