Phosphonium, tributylethyl-, bromide (PTEB) is a catalyst. A catalyst is a substance that increases the rate at which a chemical reaction proceeds by lowering the activation energy for the reaction. It does this by providing an alternative pathway for the reaction to occur in, or through its effect on the reactants and products. PTEB has been used as a catalyst in organic synthesis because of its high activity. The chloride anion is found in solid catalysts such as PTEB and can be substituted with other halides to alter their properties. Chloride impurities in PTEB are difficult to remove without affecting the structure of the molecule. Hydroxyl groups are functional groups that are often present in organic molecules, such as alcohols and esters. Copper complexes can be formed with molecules containing hydroxyl groups, such as PTEB. For example, copper(II) acetate reacts with PTEB to form copper(
