Novel Pd-and Au-catalyzed molecular transformations have been developed through the modification of ligands and counter anions which showed high reactivity and selectivity. A variety of Norbornane derivatives have been synthesized and successfully used in the Pd-catalyzed asymmetric intramolecular hydroamination of alkynes. The newly prepared (R, R)-methyl norphos and (R, R)-toly renorphos afforded N-containing heterocyles in high yields and high enantio-selectivity. Moreover, novel Pd-catalyzed allylative dearomatization and three-component cycloaddition were developed. We have succeeded in development of cationic Au-catalyzed hydroalkoxylation and hydrothiolation. Moreover, we also succeeded in construction of thienocarbazole frameworks via a new Au-catalyzed cascade cyclization of arydiynes, which was further applied in the synthesis of D-A-D organic electronic materials. Various O-, S-and N-containing heterocyles bearing diiodine substituents have been synthesized through the facile and efficient electrophilic iodocyclizations.

通过配体和抗衡阴离子的修饰，开发了新型钯和金催化的分子转化，具有高反应性和选择性。多种降冰片烷衍生物已被合成并成功用于钯催化的炔烃不对称分子内氢胺化反应。新制备的(R,R)-甲基去甲磷和(R,R)-甲基去甲磷以高产率和高对映选择性提供含氮杂环。此外，还开发了新型钯催化烯丙基脱芳构化和三组分环加成反应。我们成功开发了阳离子金催化的氢烷氧基化和氢硫醇化。此外，我们还通过新型Au催化芳基炔级联环化成功构建了噻吩并咔唑骨架，并进一步应用于D-A-D有机电子材料的合成。通过简单有效的亲电碘环化合成了各种带有二碘取代基的含O、S和N的杂环。
