Fullerene tectonics. Part 1. A programmed precursor to C60
Soluble polycyclic tectonic building blocks for C60 have been prepared by the cyclotrimerisation of aromatic ketones. Electron impact fragmentation pathways are described.
Palladium-catalyzed alkyne insertion/reduction route to trisubstituted olefins
A new route to trisubstituted olefins through a palladium-catalyzed alkyne insertion/reduction reaction with unactivated alkyl iodides is reported. The reaction proceeds under mild conditions and tolerates a range of functional groups and substitution patterns. Preliminary mechanistic inquiry suggests that the transformation may proceed through a hybrid radical/organometallic pathway.

Stereoselective Cyclization of 2-(Bromophenyl)- and 2-(Iodophenyl)alkynes Catalyzed by Palladium(0) Complexes
The Pd(II)-intermediate generated by intramolecular arylation of alkynes can be further cross-coupled with phenylzinc chloride to recycle the Pd(0) catalyst and give stereodefined exocyclic indans and tetralins.For example, (Z)-1-benzylideneindan can be o
