2,3‐Diboratabutadiene Complexes of Group 4 Metals and their Donor‐Induced Oxidative Cleavage to Methyleneboranes

ChemistryEurope, EarlyView.
GA: We here report the first perarylated 2,3‐diboratabutadiene dianion and its reaction with Cp2MCl2 (M = Zr, Hf) to afford unprecedented 2,3‐diboratabutadiene π‐complexes with unique coordination modes. Addition of an N‐heterocyclic carbene (NHC) to the complexes gives rise to the donor‐induced oxidation of the BB bond, resulting in two separate NHC ...

Boronate‐Type‐Controlled Regioselective Catalytic [2 + 2 + 2] Cyclotrimerization for Synthesis of Polysubstituted 2‐ and 3‐Borylated Pyridines

ChemistryEurope, EarlyView.
Ring the boron, not the bell: cyclotrimerization of borylated diynes with nitriles using Co and Ru catalysts allows the efficient synthesis of a wide variety of borylated pyridines with high regioselectivity, paving the way for multiple post‐functionalizations.

Investigating di‐n‐Butylcalcium

ChemistryEurope, EarlyView.
A detailed synthetic, crystallographic, and spectroscopic investigation demonstrates that the hitherto elusive di‐n‐butylcalcium is accessible and stable at low temperature, and can be used for deprotometallation reactions. The synthesis and detailed characterization by NMR spectroscopy of di‐n‐butylcalcium are reported. The reaction of [Ca{N(SiMe3)2}2.
