2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Electric Literature of C9H10O4

A free radical alkylation of quinones with olefins was written by Liu, Shuai;Shen, Tong;Luo, Zaigang;Liu, Zhong-Quan. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2019.Electric Literature of C9H10O4 This article mentions the following:

We demonstrated herein an Fe(III)-mediated radical alkylation of quinones. A wide range of bioactive mols. with quinone motifs could be rapidly synthesized by using readily available and inexpensive NaBH4/NaBD4 with alkenes at room temperature under open flask conditions. In the experiment, the researchers used many compounds, for example, 2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7Electric Literature of C9H10O4).
