Two competing reactions ensue when trialkylsilanes HSiR′3 are treated with aliphatic aldehydes RCHO in the absence of a solvent and using a nickel catalyst (obtained by the treatment of anhydrous NiCl2 with a trialkylsilane); one gives an alcoxysilane RCH2OSiR′3, the other an ether oxide (RCH2)2O and a siloxane (R′3Si)2O. By variation of the reaction conditions, either reaction can be made exclusive
