Benzyltriethylammonium chloride is used as a catalyst in the preparation of 2-phenylbutyronitrile from phenyl acetonitrile. It is involved in the Knoevenagel condensation of carbonyl compounds with active methylene compounds to give olefinic products. It acts as a phase transfer catalyst used in the alkylation reaction. It reacts with 1H-Pyridine-2-thione to get 2-Benzylsulfanyl-pyridine.
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.
