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

Beilstein 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 ...

Borylation of Aryl Halides Induced by Visible Light Under Open‐To‐Air Environment

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
Borylation of aryl halides was successfully achieved by a sustainable protocol which involved a purely organic confined medium, visible light as energy source under an open‐to‐air environment. Experimental and computational investigations evidenced that the reaction occurred through the formation of a ground–state complex generated by hydrogen bonding.

Organo-sulfur phosphorus chemistry

, 1998
P-organo-substituted dithiadiphosphetane disulfides have been prepared by the reaction of ferrocene and arenes with P4S10. Reaction of these compounds and Lawesson's reagent with alkenes, 2,3-dimethylbutadiene and other compounds gave organo-sulfur ...

Reaction of 2,2,4,4-tetrakis(trifluoromethyl)-1,3-dithiethane with N-vinyl compounds

Beilstein Journal of Organic Chemistry, 2013
The reaction of hexafluorothioacetone dimer (2,2,4,4-tetrakis(trifluoromethyl)-1,3-dithiethane, 1) with vinylamides leads to the rapid formation of [2 + 2] cycloadducts: 4-amino-2,2-bis(trifluoromethyl)thietanes.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

One-pot cross-enyne metathesis (CEYM)–Diels–Alder reaction of gem-difluoropropargylic alkynes

Beilstein Journal of Organic Chemistry, 2013
Propargylic difluorides 1 were used as starting substrates in a combination of cross-enyne metathesis and Diels–Alder reactions. Thus, the reaction of 1 with ethylene in the presence of 2nd generation Hoveyda–Grubbs catalyst generates a diene moiety ...
