Bis(acetonitrile)palladium(ii) p-Toluenesulfonate - Introduction
Bis(acetonitrile)palladium(ii) p-Toluenesulfonate is an important organic synthesis catalyst. Its chemical formula is [Pd(CH3CN)2]TsO, where TsO represents the tosylate ion. The following is a description of its nature, use, preparation and safety information:
1. nature:
Bis(acetonitrile)palladium(ii) p-Toluenesulfonate is a yellow solid, soluble in organic solvents such as acetonitrile and methylene chloride. It is a palladium complex with oxidation state 2 and has good stability.
2. use:
Bis(acetonitrile)palladium(ii) p-Toluenesulfonate are widely used in the field of organic synthesis, especially in inert bond activation, C- C bond formation and C- N bond formation reactions show excellent catalytic activity. It can catalyze benzoylation, olefin oxidation, olefin carbonylation and other reactions.
3. preparation method:
Bis(acetonitrile) The palladium(ii) p-Toluenesulfonate can be obtained by dissolving Pd(CH3CN)4(O2CMe)2 in concentrated sulfuric acid and then neutralizing the resulting solution with toluenesulfonic acid. During the reaction, care should be taken to control the temperature and reaction time to avoid the generation of impurities.
4. Safety Information:
Bis(acetonitrile)palladium(ii) p-Toluenesulfonate is generally stable under normal use conditions, but may decompose or emit toxic gases at high temperatures. Therefore, it is necessary to pay attention to prevent contact with oxygen during operation, and avoid high temperature and fire sources. In addition, the use of any chemical should be carried out under safe ventilation conditions, and strict compliance with relevant laboratory procedures and personal protective measures.
