An organic solvent such as chlorobenzene may also be employed. Water is essential to the reaction to make the dioxolanes, otherwise olefin oxides are produced. Hence, 4-methyl-1,3-dioxolane and 2,4-dimethyl-1,3-dioxolane were prepared from propylene oxidation, and three isomers of 2,4,5-trimethyl-1,3-dioxolane were prepared from 2-butene oxidation.

专利号:WO-2024182597-A1 优先权日:2023-03-02 标题 :Visible light driven co2 valorization 发明人:WEAVER JIMMIE D; SCHOCH TIM 权利人:THE BOARD OF REGENTS FOR THE OKLAHOMA AGRICULTURAL AND MECH COLLEGES 摘要:A method of carbamate ester synthesis wherein a first component is reacted with a cyclohexene by the addition of CO 2 , a photocatalyst, and light to produce an arylcyclohexyl carbamate ester. The first component is an amine, a carbamate salt produced from the amine, or a mixture thereof. In some embodiments, the method further includes treating the arylcyclohexyl carbamate ester with a base in the presence of an alcohol to produce an alkane carbamate ester and an arylcyclohexanol. Further, the method can include dehydrating the arylcyclohexanol in the presence of an acid to regenerate the arylcyclohexene.
