4-tert-Butylbenzaldehyde is notable as a rare example of industrial-scale electrochemistry. It is produced by BASF and Givaudan (typically as its methanol acetal) through a double anodic oxidation of 4-tert-butyltoluene on greater than 10,000 ton per year scale. [2] [3]

Ergoline is a core structure in many alkaloids and their synthetic derivatives. Ergoline alkaloids were first characterized in ergot.Some of these are implicated in the condition of ergotism, which can take a convulsive form [1] or a gangrenous form.
Amygdalin 2 H 2 O HCN benzaldehyde 2 × glucose 2 × Benzaldehyde contributes to the scent of oyster mushrooms (Pleurotus ostreatus). Reactions Benzaldehyde is easily oxidized to benzoic acid in air at room temperature, causing a common impurity in laboratory samples. Since the boiling point of benzoic acid is much higher than that of benzaldehyde, it may be purified by distillation. Benzyl ...
Substrates are broadly limited to methyl ketones and secondary alcohols oxidizable to methyl ketones, such as isopropanol.The only primary alcohol and aldehyde to undergo this reaction are ethanol and acetaldehyde, respectively. 1,3-Diketones such as acetylacetone also undergo this reaction. β-ketoacids such as acetoacetic acid will also give the test upon heating.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
A mixture of 3-methylbut-3-en-1-ol and 3-methylbut-2-en-1-ol may also be used. These starting materials are obtained from a reaction between isobutene and formaldehyde: [3] CH 3 CH 3 CCH 2 + CH 2 O → (CH 3) 2 CHCH 2 CHO. Finally, in beer the compound is produced via a reaction between the amino acid leucine and reductones in the malt. [4]
The reaction between menthone ((2S,5R)-2-isopropyl-5-methylcyclohexanone) and anisaldehyde (4-methoxybenzaldehyde) is complicated due to steric shielding of the ketone group. This obstacle is overcome by using a strong base such as potassium hydroxide and a very polar solvent such as DMSO in the reaction below: [ 19 ]
