• The <I>in situ</I> reaction of dialkoxydichlorosilanes, such as dimethoxy-, diethoxy-, dipropoxy-, dibutoxy-, and diisobutoxydichlorosilane, with isoprene and magnesium in tetrahydrofuran (THF) was investigated. It was found that the double annelation product, <I>i.e.</I>, 2,7-dimethyl-5-silaspiro[4.4]nona-2,7-diene (<B>1</B>), was obtained from diethoxy-, dipropoxy-, and dibutoxydichlorosilane in 87.0, 65.2, and 66.5% yields respectively. On the other hand, the reaction of dimethoxy- and diethoxydichlorosilane with butadiene and magnesium in THF gave 5-silaspiro[4.4]nona-2,7-diene (<B>7</B>) in 20.7 and 35.4% yields respectively. Several silaspirononane derivatives were synthesized from <B>1</B>.
