Versuchsvorschrift

In detail, in Japanese Patent Laid-Open Publication No. 221285/1990 for example, a solution of an indenyl lithium salt prepared from indene and n-butyllithium is slowly added to a dimethyldichlorosilane solution, and they are reacted with each other overnight to obtain dimethyldi(1-indenyl)silane in a 71% yield. In Japanese Patent Laid-Open Publication No. 268307/1992, dimethyldi (2-methyl-1-indenyl) silane is obtained in a 16% yield in a manner similar to the above.
