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).

Application

p-Tolualdehyde may be employed as growth substrate in the culture medium of the strains of Pseudomonas putida.
p-Tolualdehyde may be used in the preparation of (E)-3-(4-methyl-phen-yl)-1-(1,3-thia-zol-2-yl)prop-2-en-1-one. It may be used in the preparation of (Z)-trisubstituted allylic alcohols.
