Synthesis of a series of fluorine-rich ullazines I and II via well-controlled cycloaromatizations of highly electron-deficient alkynes was reported. Specifically, three sym.-functionalized and three unsym.-functionalized ullazine cores were constructed from 1-(2,6-dialkynylphenyl)-1H-pyrroles via controlled electrophilic cyclizations of highly electron-poor pentafluorosulfanylated (i.e., SF5-containing)phenylethynyl moieties onto the pyrrole. While the diminished reactivity of the electron-poor alkynes was initially problematic, this feature was subsequently found to be pivotal in facilitating thermal control of mono- vs. double 6-endo-trig ring-closure in the key step. Iodinated ullazine products were shown to undergo further facile transformation into more complex unsym. targets. The synthetic strategies reported herein granted access to a host of sym.- and unsym.-decorated fluorine-rich ullazines with potential value as light-harvesting materials (e.g., dye-sensitized solar cells, organic photovoltaics) or as advanced intermediates for further synthetic elaboration.

2,5-Dimethoxytetrahydrofuran(cas: 696-59-3) is a member of ether. Friedel Crafts reaction, for example, adds an alkyl or acyl group to aromatic ethers when they react with an alkyl or acyl halide in the presence of a Lewis acid as a catalyst.Related Products of 696-59-3
