synthetic organic chemistry. We report a new approach to alkene arylation using diaryliodoniumsalts and Cu catalysis. Using a range of simple alkenes, we have shown that the product outcomes differ significantly from those commonly obtained by the Heck reaction. We have used these insights to develop a number of new tandem and cascade reactions that transform readily available alkenes into complex arylated
Access to 1,3-disubstituted cyclohexenes from zirconocenes containing a latent electrophilic allylic fragment is described. Requiring a specific conformation, 6-endo-trig cyclisation is based on the TMSOTf-mediated generation of a stabilized carbocation.
