Abstract

The reactivity of hexamethylcyclotrisiloxane (D3) towards BeCl2, BeBr2, BeI2 and [Be3Ph6]3 was investigated. While BeCl2 only showed unselective reactivity, BeBr2, BeI2 and [Be3Ph6] cleanly react to the trinuclear complexes [Be3Br2(OSiMe2Br)4], [Be3I2(OSiMe2I)4] and [Be3Ph2(OSiMe2Ph)4]. 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.
