Regioselective carbon–carbon bond formation of 5,5,5-trifluoro-1-phenylpent-3-en-1-yne
Beilstein Journal of Organic Chemistry, 2013 The regioselective carbon–carbon bond formation was studied using 5,5,5-trifluoro-1-phenylpent-3-en-1-yne as a model substrate, and predominant acceptance of electrophiles β to a CF3 group as well as a deuterium trap experiment of the lithiated species ...

Three step synthesis of single diastereoisomers of the vicinal trifluoro motif
Beilstein Journal of Organic Chemistry, 2009 A three step route to single diastereoisomers of the vicinal trifluoromethyl motif is described. The route starts from either syn- or anti-α,β-epoxy alcohols and takes a direct approach in that each of the three steps introduces a fluorine atom in a ...

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 2, 5 February 2026.The complete series of 1,2‐bis(trihalogenosilyl)benzenes with F, Cl, Br, and I is synthesized and structurally characterized. The fluorinated compound binds up to two F− ions, one of them in a bridging mode. BBr3‐induced cyclization of an alkoxylated precursor affords a tetrahalogenated 1,3‐disila‐2‐oxaindane, highlighting cooperative reactivity of ...

Crystal design using multipolar electrostatic interactions: A concept study for organic electronics
Beilstein Journal of Organic Chemistry, 2013 Using a simple synthetic protocol, heterohexacene analogues with a quadrupolar distribution of partial charges are readily available. In contrast to most other acenes, these compounds crystallize with a slipped-stack, brickwork-like packing which is ...

Diastereoselectivity in the Staudinger reaction of pentafluorosulfanylaldimines and ketimines
Beilstein Journal of Organic Chemistry, 2013 β-Lactams were diastereoselectively formed by the reaction of SF5-containing aldimines, or an SF5-containing ketimine, with benzyloxyketene in a conrotatory ring closure process. Imine formation and cyclization were possible in spite of the acidification

The preferred conformation of erythro- and threo-1,2-difluorocyclododecanes
Beilstein Journal of Organic Chemistry, 2012 Cyclododecane adopts a square-like structure with corner and edge CH2 groups. In this study erythro- and threo-1,2-difluorocyclododecanes were prepared to explore whether the two vicinal C–F bonds, with different relative configurations, preferably ...
