Abstract
In redox-transmetallation protolysis (RTP) reactions in tetrahydrofuran (thf) between excess scandium or cerium metal, Hg(C6F5)(2) and 3,5-dimethylpyrazole (Me(2)pzH) in silicone greased Schlenk flasks, formation of the 3,5-dimethyl-1-pyrazolyl(dimethyl)siloxide (Me(2)pzSiMe(2)O) ligand was observed. Thus the former reaction gave [Sc-2(Me(2)pz)(4)(Me(2)pzSiMe(2)O)(2)] 1 in good yield, whilst the latter gave a mixture of [Ce4O(Me(2)pz)(9)(Me(2)pzSiMe(2)O)(2)] 2 a, [Ce4O(Me(2)pz)(11)] 2 b, both mixed oxidation state species, and the Ce-IV complex [Ce(Me(2)pz)(4)(Me(2)pzH)] 2 c.
