Investigating Tetrel-Based Neutral Frustrated Lewis Pairs for Hydrogen Activation

Tetrel Lewis acids are a prospective alternative to commonly employed neutral boranes in frustrated Lewis pair (FLP) chemistry. While cationic tetrylium Lewis acids, being isolobal and iso(valence)electronic, are a natural replacement to boranes, neutral t ...

Supramolecular polymers based on dative boron–nitrogen bonds

Kay Severin, Nicolas Luisier, Erin Sheepwash

Heteroditopic monomers containing an arylboronate ester and a dialkyl-4-aminopyridine group aggregate via dative boron–nitrogen bonds to give main chain supramolecular polymers. The degree of polymerization can be tuned by changing the electronic and steri ...

Covalent Capture of Nitrous Oxide by N-Heterocyclic Carbenes

Rosario Scopelliti, Kay Severin, Matthew Wodrich, Euro Solari, Alexander Tskhovrebov

A good catch: N-heterocyclic carbenes (NHCs) form stable adducts with nitrous oxide (N2O) under mild reaction conditions. The adducts display unique reactivity as evidenced by an alkylation reaction which leads to a rupture of the NN bond. ...

Dative boron–nitrogen bonds in structural supramolecular chemistry: multicomponent assembly of prismatic organic cages

Rosario Scopelliti, Kay Severin, Kurt Schenk, Erin Sheepwash, Burçak Içli

The multicomponent reaction of diboronic acids with a catechol and a tripyridyl linker results in the formation trigonal prismatic cages. The cages feature six dative boron–nitrogen bonds as structure-directing elements. The size of the cages can be varied ...

Pd(0)-Catalyzed Oxy- and Aminoalkynylation of Olefins for the Synthesis of Tetrahydrofurans and Pyrrolidines

Jérôme Waser, Stefano Nicolai

The first Pd(0)-catalyzed intramolecular oxy- and aminoalkynylation of nonactivated olefins is reported. The reaction gives access to important tetrahydrofuran and pyrrolidine heterocycles with high diastereoselectivity. The unique synthetic potential of a ...

The synthesis and characterisation of bis(phosphane)-linked (eta(6)-p-cymene)ruthenium(II)-borane compounds

Paul Joseph Dyson, Rosario Scopelliti

The reaction of [(η6-p-cymene)RuCl2]2 with some bis(phosphane) ligands (dppm, dppe, dppv, dppa, dpp14b, dppf) has been investigated. In general mixtures of products were obtained, although the pendant phosphane complexes [( ...

Studies on the synthesis, structure and reactivity of heterocyclic metallonitridophosphinates

T-BuP(NH2)2 reacts with base-stabilized group 13 tri-hydrides with adduct formation (THF-BH3), with redn. to give t-BuPH2 (Me3N-AlH3) and with elimination of H22 and formation of a metallonitridophosphinate (Me3N-GaH3). In contrast, the reaction with Cp*Ti ...
