- Stereoselective syntheses of spirane bridged semi-titanocenes
-
The synthesis of bidentate cyclopentadienyl-alkoxide ligands and their complexation to titanium are described. The focus has been on methodology for stereoselective synthesis of ansa half-sandwich titanocenes with rigid C 2- and C3-b

- Strain-promoted azide-alkyne cycloadditions of benzocyclononynes
-
Preliminary studies related to the design and development of new cycloalkyne reagents for metal-free click coupling are reported. Cyclononynes are more stable than cyclooctynes, and the robust benzocyclononyne platform offers spontaneous reactivity toward

- 4a-Methyl-4aH-fluorenes
-
The monobenzo derivative (1) of 3a-methyl-3aH-indene and its methyl derivative (3) have been synthesised; although isolable they are reactive, undergoing autoxidation, dimerisation, and other cycloadditions, thermal and acid catalysed aromatisation to fluorenes, and photochemical rearrangement to naphthalenes.
