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

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

Chemistry – A European Journal, EarlyView.
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.
