is it true that when di keto compounds are formed as products after oxidation with hot KMnO4 they break up further????even when we r nt using HIO4

I don't know what a diketo is.

That being said, Aldehydes are further oxidized to carboxylic acids generally.

And ketones are not further reduced as there is no available hydrogen to use.

[Ankesh]

compounds like (CH3-CO-CO-COOH) are diketo compounds..(di ketones)
i know aldehydes are further oxidised to carboxylic acid if hydrogen is present(everyone knows that)..what i am asking is why do the diketo compounds break up further even when not using HIO4

[AnkurGel]

An alkyne (R-CC-R^|) when treated with KMnO⁴ in neutral medium gives diketone (R-CO - CO-R^|.
even if some heat is provided or acquired, it will consequently break to form carboxyilic acids to give (RCOOH and R^|COOH). So yeah, it's true that a diketone compound formed after oxidation and breaks further in hot KMnO4.

ooo, that's cool. Thanks
