In the presence of gold(I)–phosphine catalysts, alkenyl- and arylsilanes undergo intramolecular cyclisation reactions onto appendant alkyne moieties to afford 1-silaindene derivatives. The reaction pathways vary depending on the substituent on silicon.

Abstract
The rhodium-catalyzed addition reaction of arylboronic acids to β-aryloxyacrylates gives 3,3-diarylpropanoates in good yields. The double arylation reaction proceeds via the intermediate cinnamates generated by β-oxygen elimination.

A range of arylboronic acids undergo a homocoupling reaction in the presence of catalytic amount of gold salts to yield symmetrical biaryls. Alkenylboronic acids, arylboronic esters, and arylborates also participate in the gold-catalyzed homocoupling reaction.

2-Silyl- and 2-borylbiphenyls have been synthesized by the palladium-catalyzed reaction of biphenylene with hydrosilanes and a hydroborane, respectively, via the cleavage of the four-membered ring of biphenylene. Under similar conditions, the C–C bond of biphenylene undergoes formal σ-bond metathesis with various intermetallic linkages to afford 2,2′-bis(metallo)biphenyls.
