A novel synthesis of 1,1-disubstituted 1H-indenes is described involving the Pd-catalyzed cascade reaction between o-bromophenyl-β-bromostyrenes and N-tosylhydrazones in a process comprising the consecutive formation of two Csp3–C bonds on the same carbon atom: the cross-coupling of the N-tosylhydrazone with the alkenyl bromide and the intramolecular Heck reaction on the newly formed double bond.

(Z)‐1,2‐Diaryl‐1,2‐bis(pinacolatoboryl)ethenes underwent double‐cross‐coupling reactions with 1‐bromo‐2‐[(Z)‐2‐bromoethenyl]arenes in the presence of [Pd(PPh3)4] as a catalyst and 3 M aqueous Cs2CO3 as a base in THF at 80 °C. The double‐coupling reaction gave multisubstitutednaphthalenes in good to high yields. Annulation of 1,2‐bis(pinacolatoboryl)arenes with bromo(bromoethenyl)arenes in the presence
