Abstract:
A method for synthesizing silasesquioxane metal complexes, said method comprising suspending:(a) a metal compound selected from the group consisting of halides, C.sub.1 to C.sub.20 alkyl or aryl compounds which do not contain a beta hydrogen atom, silyl, fluorenyl, indenyl and/or cyclopentadienyl compounds, in which individual ligands optionally may be substituted by C.sub.1 to C.sub.4 alkyl, C.sub.1 to C.sub.4 alkylsilyl, alkoxy, aryl or arylsilyl groups, oxides, imides, amides, alkoxides, and mixed compounds thereof of a metal from the 4.sup.th to the 7.sup.th subgroups of the Periodic Table of the Elements; and(b) at least one silasesquioxane of formula I:(R.sup.1 SiO.sub.1,5).sub.n (R.sup.2 SiO.sub.1,5).sub.m ((H).sub.p (B).sub.q (O).sub.r))whereinR.sup.1 is C.sub.5 to C.sub.10 cycloalkyl;R.sup.2 is OH;B is H, OH, halogen, alkoxy or SiR.sup.3.sub.y, wherein R.sup.3 is C.sub.1 to C.sub.4 alkyl, aryl, or SiMe.sub.2 (CH.sub.2).sub.s CH.dbd.CH.sub.2, SiMe.sub.2 (CH.sub.2).sub.s CH.sub.2 CH.sub.2 A, SiMe.sub.2 (CH.sub.2).sub.s CHACH.sub.3, wherein A represents OH, COOH, NH.sub.2, SO.sub.3 --, COO--, and s represents 1 to 20,y represents 2 or 3, andR.sup.1 and R.sup.3 can be functionalized by halogen or OH, andn is 6;m is 0 or 1;p is 0 to 4;q is 0 to 2; andr is 0 to 2;in an organic solvent with stirring at -80.degree. C. to +110.degree. C., and removing the resulting reaction product at room temperature.
