【摘要】:自從1991年Arduengo第一次分離得到穩(wěn)定的游離N-雜環(huán)卡賓以來(lái),其作為一種高效的有機(jī)催化劑得到了迅速的發(fā)展.由于N-雜環(huán)卡賓的極性反轉(zhuǎn)特性,它在有機(jī)合成中構(gòu)建復(fù)雜分子的地位舉足輕重.一些特定的路易斯堿及氧化劑可誘導(dǎo)卡賓與羰基化合物形成Breslow中間體、烯醇化合物和高烯醇化合物,這些中間體極大地拓展了卡賓的應(yīng)用范圍.綜述了近幾年N-雜環(huán)卡賓在催化有機(jī)反應(yīng)中的研究進(jìn)展,如催化安息香縮合反應(yīng)、Stetter反應(yīng)、a~3-d~3極性反轉(zhuǎn)反應(yīng)、環(huán)合反應(yīng)和氟化反應(yīng)等.
[Abstract]:Since 1991, when Arduengo was separated for the first time to obtain stable free N-heterocyclic carbene, it has been developed rapidly as an efficient organic catalyst. N- heterocyclic carbene plays an important role in the construction of complex molecules in organic synthesis due to its polar reversal characteristics. Some specific Lewis bases and oxidants can induce carbene and carbonyl compounds to form Breslow intermediates, enol compounds and high enol compounds. These intermediates greatly expand the application of carbene. The research progress of N-heterocyclic carbene in catalytic organic reactions such as catalytic benzoin condensation, Stetter reaction, a~3-d~3 polarity reversal reaction, cyclization reaction and fluorination reaction were reviewed.
