New iridium(I) complexes, bearing a bulky NHC/phosphine ligand combination, have been established as extremely efficient hydrogenation catalysts that can be used at low catalyst loadings, and are compatible with functional groups which are often sensitive to more routinely employed hydrogenation methods.

It has been developed to disseminate open access research outputs, expose data about those outputs, and enable the management and persistent access to Strathclyde's intellectual output. A novel chiral magnesium bisamide has enabled the development of effective asymmetric deprotonation protocols at substantially more elevated temperatures. This new, structurally simple, C 2 -symmetric magnesium complex displays excellent levels of asymmetric efficiency and energy reduction in the synthesis of enantioenriched enol silanes.

Synthesis of 7-Aryl-1,8-naphthyridines via Addition of Aryl Boronic Acids to 1,8-Naphthyridine N-Oxides. -The method is not sensitive to moisture or air and can be extended to other electron-deficient N-oxides [cf. (XII), (XIV) and (XVI)] with a different success. The process can further be applied to the synthesis of 6,7-diaryl--1,8-naphthyridines when 6-halosubstituted substrates such as (VII) are employed. -(BENNIE, L. S.; BURTON, P. M.; MORRIS*, J.
