Description:
<jats:title>Abstract</jats:title><jats:p>The reactivity of hexamethylcyclotrisiloxane (D<jats:sub>3</jats:sub>) towards BeCl<jats:sub>2</jats:sub>, BeBr<jats:sub>2</jats:sub>, BeI<jats:sub>2</jats:sub> and [Be<jats:sub>3</jats:sub>Ph<jats:sub>6</jats:sub>]<jats:sub>3</jats:sub> was investigated. While BeCl<jats:sub>2</jats:sub> only showed unselective reactivity, BeBr<jats:sub>2</jats:sub>, BeI<jats:sub>2</jats:sub> and [Be<jats:sub>3</jats:sub>Ph<jats:sub>6</jats:sub>] cleanly react to the trinuclear complexes [Be<jats:sub>3</jats:sub>Br<jats:sub>2</jats:sub>(OSiMe<jats:sub>2</jats:sub>Br)<jats:sub>4</jats:sub>], [Be<jats:sub>3</jats:sub>I<jats:sub>2</jats:sub>(OSiMe<jats:sub>2</jats:sub>I)<jats:sub>4</jats:sub>] and [Be<jats:sub>3</jats:sub>Ph<jats:sub>2</jats:sub>(OSiMe<jats:sub>2</jats:sub>Ph)<jats:sub>4</jats:sub>]. These unprecedented bromide, iodide and phenyl transfer reactions from a group II metal onto silicon offer a versatile access to previously unknown diorgano bromo and iodo silanolates.</jats:p>
