The synthesis of complex cyclic compounds is extremely challenging for organic chemists. Many transition-metal-salt-mediated cyclizations are reported in literature. Hg(II) salts have been successfully employed in cyclizations to form complex heterocyclic and carbocyclic structures that are impossible to synthesize with other transition metal salts. In this review, we have summarized cyclization reactions that are performed with Hg(II) salts. These salts are also successfully applied in stoichiometric or catalytic amounts to form complex cyclic structures and natural products.

汞(II)盐介导的不饱和键环化反应研究进展


复杂环状化合物的合成对于有机化学家来说极具挑战性。文献报道了许多过渡金属盐介导的环化。 Hg(II)盐已成功用于环化，形成复杂的杂环和碳环结构，而这些结构是其他过渡金属盐无法合成的。在这篇综述中，我们总结了用 Hg(II) 盐进行的环化反应。这些盐也成功地以化学计量或催化量应用以形成复杂的环状结构和天然产物。
