| | Definition | ChEBI: A tolualdehyde compound with the methyl substituent at the 4-position. | | Synthesis Reference(s) | Journal of the American Chemical Society, 105, p. 7175, 1983 DOI: 10.1021/ja00362a028Tetrahedron Letters, 29, p. 6265, 1988 DOI: 10.1016/S0040-4039(00)82321-7 | | General Description | p-Tolualdehyde (4-Methylbenzaldehyde) is an aromatic aldehyde. It has been generated as major oxygenated product during the UV light irradiated oxygenation of p-xylene, via photoinduced electron transfer mechanism. It undergoes condensation reaction with diiron μ-ethylidyne complex to afford μ-vinylcarbyne complex (92% yield). | | Flammability and Explosibility | Notclassified | | Purification Methods | Steam distil the aldehyde, dry it with CaSO4, then fractionally distil it.
