Key Points

Gold-catalyzed coupling allows selective incorporation of silyl moieties into newly formed compounds, enhancing synthetic versatility.
This method leads to successful reactions involving diazonium salts while minimizing undesired byproducts with corresponding boryl groups.
Cross coupling occurs specifically with B,Si-bifunctional building blocks, indicating a controlled reaction environment.
Such findings may enable broader applications in synthetic chemistry for new material development.

Implication

Gold-catalyzed coupling improves silyl incorporation in reactions with diazonium salts, indicating new synthetic pathways.

Abstract

The gold-catalyzed cross coupling of diazonium salts enables the selective coupling of silyl over boryl moieties. So far only aryl and vinyl B,Si-bifunctional building blocks have been coupled to obtain...
