CO bond formation between terminal alkenes/benzyl alcohols as an arylcarboxy surrogate and carbonyl compounds in a biodegradable deep eutectic solvent (DES) based on choline chloride and urea was performed. By employment of TBAI as catalyst and TBHP as oxidant, various derivatives of carbonyl compounds were benzylated in α position in good to high yield at 90 °C. Moreover, α-oxybenzoylation of diethyl
在基于氯化胆碱和尿素的可生物降解的深共熔溶剂(DES)中,作为芳基羧基替代物的末端烯烃/苄醇与羰基化合物之间进行了C O键形成。通过使用TBAI作为催化剂和TBHP作为氧化剂,羰基化合物的各种衍生物在90℃下以良好或高产率在α位被苄基化。此外,在上述DES中,通过使用NaI作为催化剂和TBHP作为氧化剂,在上述DES中进行了丙二酸二乙酯与羧酸的α-氧基苯甲酰化反应。
