The chronic toxicity of hexane is attributed to hexane-2,5-dione. The symptoms are tingling and cramps in the arms and legs, followed by general muscular weakness. In severe cases, atrophy of the skeletal muscles is observed, along with a loss of coordination and vision problems. [2] Similar symptoms are observed in animal models.
Amarnath's work showed that the diastereomers of 3,4-disubstituted-2,5-hexane diones react at different rates. In the commonly accepted mechanism, these diones would go through a common enol intermediate, meaning that the meso and d,l -racemic isomers would cyclize at the same rate as they form from a common intermediate.
This reaction is an important approach to the formation of carbon-carbon bonds in organic molecules containing ring systems. As an example, under strong basic conditions (e.g. sodium hydroxide), hexane-2,5-dione (compound A in Figure 1) can cyclize via intramolecular aldol reaction to form the 3-methylcyclopent-2-en-1-one (compound B).

Hexane is not tremendously terrible as organic solvents go, but it isn't really something encountered much in a natural diet. (See also Hexane-2,5-dione, though of course here we're talking about miniscule amounts) Oh, and the reason not to use vegetable oil is you'd be stuck with the vegetable oil afterward because (obviously) it doesn't ...
