Final answer:
The reaction between limonene and ozone, followed by work-up with dimethyl sulfide, would involve ozonolysis and likely result in a mixture of carbonyl-containing compounds, although the exact structures are challenging to predict without further information.
Step-by-step explanation:
The question involves predicting the structure of the products resulting from the reaction between limonene, a natural terpene, and ozone, followed by work-up with dimethyl sulfide. The reaction between an alkene like limonene and ozone is called an ozonolysis. This process typically cleaves the double bond and leads to the formation of two carbonyl-containing fragments. When the ozonolysis is followed by work up with a reducing agent like dimethyl sulfide, the intermediate ozonides are reduced to alcohols or carbonyl compounds without further oxidation.
Specifically, in the case of limonene, which has two double bonds, the ozonolysis would lead to the formation of an array of products depending on the double bonds that are cleaved. The presence of dimethyl sulfide indicates that the reaction work-up would likely prevent over-oxidation and perhaps generate aldehyde or ketone products, along with secondary ozonide decomposition products. However, without more detailed information about the reaction conditions and the specific limonene isomer, it is challenging to predict the exact structures of the resulting products.
