The solution was stirred for 45 minutes at −78° C. and 2.83 mL (23.06 mmol) of chlorotrimethylgermane was slowly added with a syringe. The solution was stirred for overnight. The reaction mixture was purified by column 5% ethyl acetate in hexane and distillation. ˜4.1 g white slide was obtained after recrystallization from hexane. GC-MS confirmed the desired product.
