Condensation of p-trimethylsilylbenzaldehyde with aldehydes and ketones

1. The condensation of p-trimethylsilylbenzaldehyde with aldehydes and ketones has been studied. 2. A number of tetra-substituted silanes have been prepared, the organic radicals of which contain different functional groups (carbonyl, carboxyl, hydroxyl) and their physicochemical constants have been determined. Seven of the compounds prepared were synthesized for the first time. 3. The Si-Car bond in these compounds is stable to the action of 10–20% solutions of alkalies and acids.
