O(2) activation and hydrolysis of Salan rare-earth metal alkyl complexes.
Salan ligated yttrium alkyl complex , L(1)Y(CH(2)SiMe(3))(THF) (Salan = L(1): [2-O-3,5-tBu(2)-C(6)H(2)CH(2)N(CH(3))CH(2)](2)), was exposed to an oxygen/nitrogen atmosphere to give a bimetallic alkoxide complex , [L(1)Y(mu-OCH(2)SiMe(3))](2). Whilst the lutetium counterparts (L(1)Lu(CH(2)SiMe(3))(THF)) and (L(2)Lu(CH(2)SiMe(3))(THF); L(2): [2-O-3-tBu-C(6)H(2)CH(2)N(CH(3))CH(2)](2)) were hydrolysed with moist nitrogen to afford mixed hydroxy/silyloxy complexes and ([L(1,2)Lu(mu-OSiMe(3))(mu-OH)LuL(1,2)]), respectively.
