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

Not classified

Purification Methods

Steam distil the aldehyde, dry it with CaSO4, then fractionally distil it. [Beilstein 7 IV 672.]
