Conjugated aldehydes and ketones undergo reaction with Me2PhSiBpin (pin: pinacolato) catalyzed by Au nanoparticles supported on TiO2 forming exclusively the β-borylation products, via the intermediate formation of the labile silaboration adducts. This chemoselectivity pathway is complementary to the so far known analogous reaction catalyzed by other metals, where β-silylation occurs instead. β-Borylation also occurs with pinBBpin under identical reaction conditions in a variety of conjugated carbonyl compounds, including esters and amides which are unreactive in their attempted Au-catalyzed silaboration.

A series of β,γ-unsaturated ketones were isomerized to their corresponding α,β-unsaturated ketones by the introduction of DABCO in iPrOH at room temperature. The endo-cyclic double bond (β,γ-position) on ketone was rearranged to exo-cyclic double bond (α,β-position) under the reaction conditions.
InBr3-Catalyzed Alkynylation and Allylation of Acid Chlorides: A Facile Synthesis of Alkynyl and Allyl Ketones

Alkynylsilanes and allyltrimethylsilane undergo smooth coupling with acid chlorides in the presence of 5 mol% of indium tribromide under mild conditions to afford the corresponding α,β-acetylenic ketones and β,γ-unsaturated ketones in excellent yields in a short reaction time with high selectivity.
