1. Reinvestigation of a catalytic, enantioselective alkene dibromination and chlorohydroxylation, 2. Double cross-coupling reactions of siloxaborolates, 3. The enantioselective synthesis of 3-substituted morpholines using computer-guided catalyst design
… to reproduce eight, putative, enantioselective dibromination and chlorohydroxylation reactions from oft-cited literature studies are described. The reactions were performed with full fidelity to the original report wherever possible. Analysis of the enantiomeric composition was performed by …

The synthesis and properties of some higher membered fused alicyclic ring systems
… Attempts to reach the heptalene structure by dibromination of methyl [0.5.5J-bicyclo-dodecatetraene carboxylate and the mild dehydrobromination with diethyl aniline failed to yield the required product, once again demonstrating that the heptalene system has not the stability which is expected …

Studies of some reactions between electrophilic halogens and various conjugated systems in which intermediates or products having rearranged double-bond systems are concerned
… of the kinetically controlled products, and dibromination, can be controlled by selective choice of the conditions of bromination and work-up. Complications associated with the reaction paths have been partly elucidated. The rates and mechanism of reversible isomerisation of 6β- to …
