Allyl phenyl ether (C9H10O) is a clear and very slight yellow liquid that is stable under normal temperatures and pressures. For the most part it is a fairly stable compound, however if it decomposes, toxic fumes can be produced, such as carbon dioxide and carbon monoxide.〔MSDS Allyl Phenyl Ether, Chemical Book. http://www.chemicalbook.com/ProductMSDSDetailCB6454708_EN.htm〕 Allyl phenyl ether is a good starting reactant for many different experiments. One experiment that it is used for is the Claisen rearrangement. Due to its structure, it can carry out the rearrangement by being in the less optimal structure where the compound appears to be sterically hindered. This position is actually necessary and can only be formed by certain compounds like allyl phenyl ether.〔Castro, Ana M. Martin. “Claisen Rearrangement over the Past Nine Decades” Chemical Reviews 104, no. 6 (2004): 2939-3006. 〕〔Yadav, G. D.; Lande, S. V., UDCaT-5: A Novel and Efficient Solid Superacid Catalyst for Claisen Rearrangement of Substituted Allyl Phenyl Ethers. Synthetic Communications 2007, 37 (6), 941-946.〕 One type of synthesis of allyl phenyl ether is through tri-liquid phase catalysis, which uses the reagents of NaOPh (C6H5NaO) and QBr (tetra-n-butylammonium bromide). Some of the factors that affect the synthesis are:〔Hsu-chin Hsiao, J. D.; Hung-shan Weng, J. D., ANALYSIS OF FACTORS AFFECTING THE SYNTHESIS OF ALLYL PHENYL ETHER BY TRI-LIQUID-PHASE CATALYSIS.
