A mixture of 240 mg (0.60 mmol) of 2-[3,5-bis(trimethylgermyl)phenyl]-2-methyl-1,3-dioxolane, 23 mg (0.090 mmol) of PPTS, 10.6 ml of acetone (excess) and 540 mg (30 mmol) of water was refluxed for 2.5hours. The reaction mixture was evaporated and extracted with ether. The extract was evaporated to give 208 mg of pale yellow crystals, which were sublimed at 70° C., 0.5mmHg to give 189 mg of white prisms, m.p.56° C. (yield 89%).
