recommendations! Published in 2022 at "European Journal of Organic Chemistry"

DOI: 10.1002/ejoc.202200901

Abstract: Abstract Two templates used in meta‐directed C−H functionalisation under metal catalysis do not direct meta‐C−H borylation under electrophilic borylation conditions. Using BCl3 only Lewis adduct formation with Lewis basic sites in the template is observed.… read more here.

DOI: 10.1016/j.chempr.2020.11.017

Abstract: Synthetic and mechanistic investigations into the C(sp2)-H borylation of various electronically diverse arenes catalyzed by bis(phosphine)pyridine (iPrPNP) cobalt complexes are reported. Borylation of various benzoate esters and arylboronate esters gave remarkably high selectivities for the… read more here.

DOI: 10.1016/j.jcat.2019.01.030

Abstract: Abstract Metal-modified covalent triazine frameworks (CTFs) have attracted considerable attention in heterogeneous catalysis due to their strong nitrogen-metal interactions exhibiting superior activity, stability and hence recyclability. Herein, we report on a post-metalation of a bipyridine-based… read more here.

DOI: 10.1016/j.jorganchem.2019.07.009

Abstract: Abstract The reaction between aryl substituted α-olefins and dichloro(diisopropylamino)borane catalyzed with Cp 2 TiCl 2 leads to trans -1-alkenyl(chlorodiisopropylamino)boranes in high yields. Aliphatic α -olefins in this reaction give borylation and hydroboration products, namely, trans… read more here.

DOI: 10.1021/acs.inorgchem.2c01667

Abstract: Second coordination sphere interactions of cyanido complexes with hydrogen-bonding solvents and Lewis acids are known to influence their electronic structures, whereby the non-labile attachment of B(C6F5)3 resulted in several particularly interesting new compounds lately. Here,… read more here.
