ZnI 2 -TESH has been found to be a novel mild and efficient reduction system. This reagent, in contrast to the traditional ionic deoxygenation systems (TFA-R 3 SiH, BF 3 ·OEt 2 -R 3 SiH, etc.), could directly deoxygenate different kinds of carbonyl compounds such as aryl aldehydes, ketones, and α,β-unsaturated enones to the corresponding hydrocarbons in moderate to excellent yields.
ZnI 2 -TESH 已被发现是一种新型温和有效的还原系统。该试剂与传统的离子脱氧体系(TFA-R 3 SiH、BF 3 ·OEt 2 -R 3 SiH等)不同,可直接对芳醛、酮和α等不同种类的羰基化合物进行脱氧,以中等至极好的收率将 β-不饱和烯酮转化为相应的烃。
