Machine Learning-Guided Development of Trialkylphosphine Ni(I) Dimers and Applications in Site-Selective Catalysis

…, JS Ward, K Rissanen, GJ Tizzard… - Journal of the …, 2023 - ACS Publications
Owing to the unknown correlation of a metal’s ligand and its resulting preferred speciation in
terms of oxidation state, geometry, and nuclearity, a rational design of multinuclear catalysts …

A catenane that is topologically achiral despite being composed of oriented rings

…, F Rizzi, D Lozano, EMG Jamieson, GJ Tizzard… - Nature Chemistry, 2023 - nature.com
Catenanes—molecules comprising two interlocking rings held together like links in a chain—are
topologically non-trivial: a catenane is a topological isomer of its separated rings, but …

When weaker can be tougher: the role of oxidation state (I) in P-vs N-ligand-derived Ni-catalyzed trifluoromethylthiolation of aryl halides

I Kalvet, Q Guo, GJ Tizzard, F Schoenebeck - ACS catalysis, 2017 - ACS Publications
The direct introduction of the valuable SCF 3 moiety into organic molecules has received
considerable attention. While it can be achieved successfully for aryl chlorides under catalysis …

…, ML Davies, K Al-Salihi, MB Pitak, GJ Tizzard… - Journal of Materials …, 2012 - pubs.rsc.org
This paper describes the synthesis of a new, yellow triphenylamine dye, 4-[2-(4-diphenylaminophenyl)vinyl]benzoic
acid] (6), with a sorption maximum at 380 nm in solution for which …

A chiral interlocking auxiliary strategy for the synthesis of mechanically planar chiral rotaxanes

…, AW Heard, MA Jinks, JM Suarez, GJ Tizzard… - Nature …, 2022 - nature.com
Rotaxanes can display molecular chirality solely due to the mechanical bond between the
axle and encircling macrocycle without the presence of covalent stereogenic units. However, …

[PDF][PDF] A chiral macrocycle for the stereoselective synthesis of mechanically planar chiral rotaxanes and catenanes

S Zhang, A Rodríguez-Rubio, A Saady, GJ Tizzard… - Chem, 2023 - cell.com
Active template auxiliary methodologies have previously been developed for the stereoselective
synthesis of chiral interlocked molecules in which the mechanical bond provides the …

showing high efficiency as catalysts with low catalytic loadings in Friedel–Crafts alkylation …

Are the crystal structures of enantiopure and racemic mandelic acids determined by kinetics or thermodynamics?

RK Hylton, GJ Tizzard, TL Threlfall… - Journal of the …, 2015 - ACS Publications
Mandelic acids are prototypic chiral molecules where the sensitivity of crystallized forms (enantiopure/racemic
compound/polymorphs) to both conditions and substituents provides a …
