Building a lewis acidic phosphorus
Using the σ- and п-donating properties of carbodiphosphorane ligands, we recently synthesized a phosphorus (III)-containing dication. It is observed to undergo interesting reactivity with PMe3, H2O and MeOH.
Isolation of a bis(oxazol-2-ylidene)-phenylborylene adduct and its reactivity as a boron-centered nucleophile
An isolable phenylborylene species supported by two oxazol-2-ylidene ligands was synthesized and structurally characterized. Computational studies revealed the presence of lone-pair electrons on the boron atom in this ...
Synthesis of N-heterocyclic carbene stabilized catecholatoborenium cations by ligand substitution
Ligand substitution is not a common procedure for the preparation of different borenium cations. This work demonstrates that the chloride ligands of several NHC-stabilized dichloroborenium cations [NHC·BCl2][X] (NHC = ...
Dihaloborenium cations stabilized by a four-membered N-heterocyclic carbene : electron deficiency compensation by asymmetric structural changes
The synthesis, characterization and X-ray analysis of dichloro- and dibromo-borenium cations stabilized by a 4-membered carbene are reported. The ligand's structural changes, atypical for similar systems, were caused by ...
Oxidative addition of water and methanol to a dicationic trivalent phosphorus centre
Our recently synthesised phosphorus dication is observed to activate water (and methanol) under reactions conditions atypical for other systems containing a non-metal centre. This particular activation described as oxidative ...
