Description

Triphenylsilanol is used as a water surrogate for regioselective Pd catalyzed allylations. A thick on germanium substrates have been produced by the electron bombardment of an evaporated thin film of triphenylsilanol.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
Triphenylsilanol is used as a water surrogate for regioselective Pd catalyzed allylations. A thick on germanium substrates have been produced by the electron bombardment of an evaporated thin film of triphenylsilanol.

Solubility
Insoluble in water.

Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents, water, moisture.
