As part of a general program to make oxygen-stabilized organoyttrium and organolanthanide complexes, they have examined synthetic routes to the simple prototypical organometallic alkoxide complex dicyclopentadienylyttrium methoxide (1). Although 1 can be produced in the reaction of ((C/sub 5/H/sub 5/)/sub 28/..mu..-H)(THF))/sub 2/ with CH/sub 3/OH or CH/sub 2/O, the potentially more direct synthesis from (C/sub 5/H/sub 5/)/sub 2/YCl(THF) and alkali-metal methoxides can take a different course. A remarkable polymetallic oxide complex can be obtained whose synthesis and structure may have important implications in organometallic oxide/alkoxide chemistry. (C/sub 5/H/sub 5/)/sub 2/YCl(THF) reacts with desolvated KOCH/sub 3/ in THF overnight at 30/sup 0/C to form a mixture of products containing some dicyclopentadienylyttrium methoxide. By use of the solvate KOCH/sub 3/ x CH/sub 3/OH, complex 1 can also be obtained from (C/sub 5/-H/sub 5/)/sub 2/YCl(THF) at -78/sup 0/C, but when the reaction is run at 30/sup 0/C for a 2-day period, the formation of complex 1 is not observed. Instead, a complex, 2, which is a minor component at low temperature, is obtained as the predominant product. 2 can be isolated in 60-70% yield by removing THF from the reaction mixture and extracting with toluene.
