Gold-Catalyzed Oxidations of 1,3-Diynamides with C(1) versus C(3) Regioselectivity: Catalyst-Dependent Oxidative Cyclizations in the C(3) Oxidation.Organic letters, 2020Co-Authors: Manisha Skaria, Mu Jeng Cheng, Yu Chen Hsu, Yan Ting Jiang, Tung Chun Kuo, Rai-shung LiuAbstract:
This work reports two distinct paths in catalytic oxidations of 1,3-diynamides with 8-Methylquinoline oxide. A typical C(1) regioselectivity was observed for aryl-substituted 1,3-diyn-1-amides, whe…
Gold-Catalyzed Oxidation of Thioalkynes To Form Phenylthio Ketene Derivatives via a Noncarbene RouteOrganic letters, 2019Co-Authors: Pankaj Sharma, Rahulkumar Rajmani Singh, Sovan Sundar Giri, Liang Yu Chen, Mu Jeng Cheng, Rai-shung LiuAbstract:
Gold-catalyzed oxidations of thioalkynes with 8-Methylquinoline oxides afford 2-phenylthioketenes that can be trapped efficiently with alcohols. The synthetic utility is manifested by terminal and internal thioalkynes over a wide scope, bearing esters, ketones, alkyl, and oxime substituents. Our density functional theory calculations suggest that gold-catalyzed oxidations of terminal and internal thioalkynes with 8-Methylquinoline oxides generate gold-bound ketene intermediates without the intermediacy of α-oxo gold carbene.
Gold-catalyzed oxidative cyclization of 4-allenyl-1-ynes with 8-Methylquinoline oxide.Organic letters, 2013Co-Authors: Rahul Kisan Kawade, Rai-shung LiuAbstract:
Gold-catalyzed oxidative cyclizations of 4-allenyl-1-ynes with 8-Methylquinoline oxide are described; diverse products are produced depending on the allenyl substituents. This reaction comprises initial formation of α-oxo gold carbenes that are attacked by allene to form allyl cation intermediates.

Ru(II)-catalyzed amidation reactions of 8-Methylquinolines with azides via C(sp(3))-H activation.Chemical communications (Cambridge England), 2015Co-Authors: Bingxian Liu, Baiquan WangAbstract:
Ru(II)-catalyzed amidation reactions of 8-Methylquinolines with azides have been developed. They are the first examples of [(p-cymene)RuCl2]2-catalyzed C(sp(3))-H bond intermolecular amidation reactions which give quinolin-8-ylmethanamines under mild reaction conditions in good yields.
Rhodium(III)-Catalyzed Alkenylation Reactions of 8-Methylquinolines with Alkynes by C(sp3)—H Activation.ChemInform, 2014Co-Authors: Bingxian Liu, Tao Zhou, Haibin Song, Baiquan WangAbstract:
The first transition-metal catalyzed alkylation of the C(sp3)—H bond of 8-Methylquinolines with internal alkynes offers a convenient synthesis of 8-allylated quinolines.
Rhodium(III)-Catalyzed Intermolecular Amidation with Azides via C(sp3)–H FunctionalizationThe Journal of organic chemistry, 2014Co-Authors: Nuancheng Wang, Haibin Song, Baiquan WangAbstract:
The amidation reactions of 8-Methylquinolines with azides catalyzed by a cationic rhodium(III) complex proceed efficiently to give quinolin-8-ylmethanamine derivatives in good yields via C(sp3)–H bond activation under external oxidant-free conditions. A catalytically competent five-membered rhodacycle has been isolated and characterized, revealing a key intermediate in the catalytic cycle.
