100 cm3 of a 0.5M solution of zinc bromide in dry tetrahydrofuran were cooled to 0° C. and stirred under argon. To this solution were added, dropwise, 100 cm3 of a 1M solution of sodium trimethylsilanolate in dry tetrahydrofuran. The mixture was allowed to warm up to ambient temperature and was stirred overnight. The mixture was filtered. The filtrate was used as a 0.25M solution of zinc trimethylsilanolate in tetrahydrofuran.
