1-Iodo-polyfluoroalkanes from polyfluoroalkoxy trimethylsilanes and iodochloro triphenylphosphorane
摘要:
Polyfluoroalkoxy trimethylsilanes R(f)CH(2)OSi(CH3)(3) (from the alcohols R(f)CH(2)OH and HMDS), react with Ph(3)PICl (from ICl and Ph(3)P) eliminating (CH3)(3)SiCl. Pyrolysis or the residues gives Ph(3)PO and pure iodides R(f)CH(2).

oxolane. The cyclized product acts as a radical precursor and adds to the olefin under UV irradiation. In addition, the difference in reactivity between 3 and 4 was clarified, and a double cyclization reaction of 4 with allylaniline was conducted.

(1H,1H-Perfluoroalkyl)phenyl- and -(p-fluorophenyl)iodoniurn triflates, fluorosulfate, sulfate (3)–(7) were synthesized in good yields by the oxidation of 1-iodo-1H,1H-perfluoroalkanes (RfCH2I) with trifluoroperacetic acid followed by treatment with triflic acid and benzene or fluorobenzene. (1H,1H,5H,5H-Perfluoropentane-1,5-diyl)bisphenylbisiodonium triflate was synthesized similarly. (trans-1H-P

conjugated dienes and enynes, and a broad array of polyfluoroalkyl iodide and oxindoles), which enables modular modification of complex drug-like compounds in one chemical step. The success of solar-driven transformation, large-scale synthesis, and the late-stage functionalization of bioactive molecules, as well as promising tumor-suppressing biological activities, highlights the potential for practical applications
