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 ...

Bis‐Dichlorosilyl Functionalized C4‐Cumulene With Unique Bonding Scenario

Chemistry – A European Journal, EarlyView.
Herein, we report a silylene‐functionalized C4‐cumulene (2) and investigate its bonding scenario employing computational methods such as NBO analysis, AIM, and energy decomposition analysis‐natural orbital for chemical valence (EDA‐NOCV). The EDA‐NOCV analysis showed that compound 2 prefers to possess electron‐sharing covalent sigma and dative covalent
