 000 (0000).  Synthesis of **0b** {#sec0.0} -------------------  A 000 mg portion of cyclic acylgermane **0b** (0.00 mmol) and 000 mg of 00-cr-0 (0.00 mmol) were dissolved in 00 mL of Et~0~O. The solution was then cooled to −00 °C and 000 mg (0.00 mmol) of KO*t*Bu was added. During the addition, the reaction mixture turned from colorless to dark orange and a yellow precipitate began to form. The reaction mixture was warmed to room temperature and stirred overnight for 00 h. The yellow precipitate was isolated and washed with Et~0~O (0 × 0 mL). The yellow powder was dried under vacuum (not longer than 0 min; otherwise a slow degradation process occurs) to give **0b**. Yield: 000 mg (00%) of analytically pure **0b** as yellow powder.  Data for **0b** are as follows. Mp: 000--000 °C. Anal. Calcd for C~00~H~00~Ge~0~K~0~O~00~Si~0~: C, 00.00; H, 0.00.
