Synthesis and structure of the polymetallic yttrium alkoxide complex Y/sub 3/(. mu. /sub 3/-OCMe/sub 3/)(. mu. /sub 3/-Cl)(. mu. -OCMe/sub 3/0/sub 3/(OCMe/sub 3/)/sub 4/(THF)/sub 2/ and related complexes: Ln/sub 3/(. mu. /sub 3/-OR)(. mu. /sub 3/-X)(. mu. /sub 3/-OR)/sub 3/ building blocks in yttrium and lanthanide alkoxide chemistry
Since factors are so important in the chemistry of yttrium and the lanthanide elements, the authors felt it was essential to obtain more structural data on the alkoxide complexes they would use as starting materials for C/sub 5/R/sub 5/ free organoyttrium and organolanthanide systems. In this report they describe the synthesis as structural features of yttrium and lanthanum alkoxide complexes which represent prototypical starting materials for synthesis of organoyttrium and organolanthanide alkoxide alkyl and hydride complexes. They have chosen Y and La because these metals are representative of late and early lanthanide chemistry, respectively, and provide diamagnetic compounds characterizable by NMR spectroscopy. To keep the spectroscopy as simple as possible they have worked exclusively with the tert-butoxide ligand which gives soluble complexes with a single /sup 1/H NMR resonance per ligand.
