Nickel(0) catalyzed oxidation of organosilanes to disiloxanes by air as an oxidant

Abstract We report here an efficient non-aqueous route to symmetrical disiloxanes from their corresponding organosilanes using Ni(COD) 2 with 3,4,7,8-tetramethyl-1,10-phenanthroline in air. Our methodology is very simple and high yielding. The reaction mechanism is also proposed.
