1-((Dimethyl(3-((2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-pentadecafluorooctyl)oxy)propyl)silyl)oxy)-3,5,7,9,11,13,15-heptakis((dimethylsilyl)oxy)-octasilsesquioxane

open access: yesMolbank
The title compound was synthesized using Pt-catalyzed hydrosilylation of octasilane POSS and allyl 1H,1H-perfluorooctyl ether. The purity and structure were determined by NMR (1H, 13C, 19F, 29Si), and MALDI TOF-MS.

An Intramolecular Frustrated Lewis‐Pair Based on a Bismuth(III) Acid Site

open access: yesChemistryEurope, Volume 4, Issue 9, September 2026.
Triflate ligands were the key for the design of a frustrated Lewis pair (FLP) that utilizes a soft bismuth(III) center as the Lewis acidic site. The acceptor properties are based on empty p orbitals generated through the ionic binding of the triflate anions to the Bi center.

Oxidative 3,3,3-trifluoropropylation of arylaldehydes

open access: yesBeilstein Journal of Organic Chemistry, 2013
A reaction between (E)-trimethyl(3,3,3-trifluoroprop-1-en-1-yl)silane (1) and arylaldehydes 2 was triggered by fluoride anions to afford aryl 3,3,3-trifluoropropyl ketones 3 in moderate to good yield.

Organo-Fluorine Compounds as Artificial Blood Substitute

open access: yesDefence Science Journal, 1980
The rate of fluoro-carbon compounds as artificial substitute for blood has been discussed. Blood is a complicated body fluid. At first glance it seems impossible that such a complicated body fluid can be replaced by artificial synthesized fluids or any substitute for this can be synthesized.

Prins fluorination cyclisations: Preparation of 4-fluoro-pyran and -piperidine heterocycles

open access: yesBeilstein Journal of Organic Chemistry, 2010
The Prins reaction was investigated using BF3·OEt2 as a Lewis acid. It has been recently demonstrated, that if BF3·OEt2 is used in stoichiometric amounts then these reactions generate fluorinated products where the BF3·OEt2 contributes fluoride ion to ...
