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

ChemistryEurope, EarlyView.
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.

Organophotoredox/Cobalt‐Catalyzed Retro‐Hydroformylation of Aldehydes

ChemistryEurope, EarlyView.
A new photoredox/cobalt retro‐hydroformylation is developed. This one‐pot two‐step process involves the in situ formation of the corresponding 1,4‐dihydropyridine as key intermediate. Under mild reaction conditions, alkenes are efficiently produced from a wide range of aliphatic α‐monosubstituted aldehydes, with high functional‐group tolerance.

Electrophilic Functionalization of Donor‐Stabilized Phosphanylboranes: A New Pathway toward Heavy 13/14/15 Parent Hydride‐Containing Compounds

ChemistryEurope, EarlyView.
A new way of obtaining mixed 13/14/15 hydride containing compounds stabilized only by a Lewis base is presented. The functionalization of IDipp·BH2PH2 (IDipp = 1,3‐Bis‐(2,6‐diisopropylphenyl)‐imidazolin‐2‐ylidene) by main group electrophiles leads to the formation of the compounds [IDipp·BH2PH2E]+ [E = H, CH3 SiEt3, Ge(SiMe3)3, SnMe3) which represent a

Skeletal Editing from Pyridine to Aniline via C‐Insertion and N‐Isomerization

ChemistryEurope, EarlyView.
A concise protocol is presented that converts pyridines into anilines by externalizing the original pyridine nitrogen at either the "ipso" or "ortho" position, which results in para or meta‐primary aniline products. A key carbene‐insertion step precedes nitrogen migration, preserving both ring size and overall structure.

Enantioselective Synthesis of Sulfinamidines via Asymmetric Rhodium–Catalyzed Imidation of Sulfenamides

ChemistryEurope, EarlyView.
In this work, a catalytic enantioselective imidation approach is presented for the preparation of enantioenriched sulfinamidines from sulfenamides, employing a chiral dirhodium(II) tetracarboxylate catalyst. This method enables the imidation of N,N‐bisalkyl sulfenamides in yields of up to 98% and enantiomeric ratios up to 98:2, with a catalyst loading ...
