Introducing the Cis‐2,3‐Bis(trifluoromethyl)cyclopropyl Chemotype: Late‐Stage Installation and Stereoelectronic Properties

ChemistryEurope, Volume 4, Issue 2, February 2026.
The cis‐2,3‐bis(trifluoromethyl)cyclopropyl chemotype is introduced. The steric demand of this motif is intermediate between that of the heptafluoroisopropyl and prefluorotertbutyl groups; yet, it induces significantly less lipophilicity than these due to its facial polarity.

Quantifying the Electrophilicity of 9(10H)‐Phenanthrenone‐ and 1‐Acenaphthenone‐Derived α, β‐Unsaturated Ketones

Journal of Physical Organic Chemistry, Volume 39, Issue 2, February 2026.
The electrophilicities (Mayr E) of the α, β‐unsaturated ketones A and B were determined by kinetic studies of their reactions with carbanions (reference nucleophiles) in DMSO at 20°C. The different reactivities of A and B were rationalized by DFT calculations.

Cyclopropenes in Photochemical Reactions

Chemistry – A European Journal, Volume 32, Issue 3, 16 January 2026.
The photochemical side of cyclopropenes. Cyclopropenes are valuable synthetic tools in organic chemistry. In particular, this review focuses on the photochemistry of cyclopropenes. The reactivity of cyclopropenes excited by irradiation is discussed showing their unique potential for organic synthesis.
