Ligand Assisted CO2 Activation and Catalytic Valorization by an NHI‐Stabilized Stannylene
ChemCatChem, Volume 14, Issue 19, October 10, 2022., 2022 A heteroleptic N‐heterocyclic imine (NHI)‐supported (aryl)stannylene enables activation and valorization of CO2 to C1 feedstock in stoichiometric and catalytic manner via ligand assisted hydroboration. Abstract The aryl(imino)stannylene MesTer[N(IDipp)]Sn could be obtained by treating NHILi (NHI=N(IDipp), IDipp=C[N‐(2,6‐iPr2C6H3)CH]2) with MesTerSnCl ...

European Journal of Inorganic Chemistry, Volume 2021, Issue 37, Page 3852-3860, October 7, 2021., 2021 Coordination and structural chemistry of fulvene‐1,1‐dithiolate [CpCS2]2− and its fluorene analogue [FluoCS2]2− with main group metals was essentially unexplored. This gave impetus to fill the gap and to accept surprises. Abstract Quaternary ammonium and phosphonium stannates(II), indates(III) and bismuthates(III) displaying dianionic S,S dithiolate ...

European Journal of Inorganic Chemistry, Volume 2021, Issue 23, Page 2211-2224, June 21, 2021., 2021 A novel phosgene‐free approach towards isocyanates using aminosilanes and carbon dioxide is reported. The four‐step overall synthesis of isocyanates includes a pressure supported CO2 insertion into the Si−N bonds to form O‐silylcarbamates and their transformation into isocyanates by thermal treatment.

Cornforth–Evans Transition States in Stereocontrolled Allylborations of Epoxy Aldehydes
Chemistry – A European Journal, Volume 26, Issue 39, Page 8639-8650, July 14, 2020., 2020 Felkin–Anh or Cornforth–Evans? The allylboration of epoxy aldehydes provides a stereoselective access to contiguously functionalized alkyl chains as found in a myriad of natural products. Studying this transformation in experiment and in silico disclosed high stereoselectivities, the mode of asymmetric induction, and enabled the predictable application
