K2S2O8–Promoted C3-Bromination of Heteroarenes with Sodium Bromide

Yucai Tang, Jiale Liu, Jiaming Huang, Yao Duan et autres

A K2S2O8-promoted C3-bromination of heteroarenes using sodium bromide was developed. This method provides efficient access to a broad array of C3-brominated heteroarenes, including quinoxalin-2(1H)-ones, cinnolin-4(1H)-ones, coumarins, and oxazinone derivatives, in moderate to good yields (38 examples). Notably, this approach is applicable to …

Visible-Light-Enabled Fluorosulfonylalkynylation of Alkenes

Yucai Tang, Qiangsheng He, Jiale Liu, Jiaming Huang et autres

A visible-light-enabled fluorosulfonylalkynylation of alkenes has been developed using alkynyl sulfonyl fluorides as bifunctional reagents under catalytic aryl diazonium activation. This photocatalyst- and oxidant-free protocol affords diverse 1-sulfonyl fluoride-2-alkynyl adducts in good yields with excellent chemoselectivity and a broad scope, enabling late-stage …

Visible-Light-Induced Organic-Dye-Catalyzed Bromination of Activated Alkenes with Sodium Bromide

Yucai Tang, Jiale Liu, Jiaming Huang, Shian Deng et autres

The direct introduction of a bromine atom into organic molecules is valuable because of its versatility in synthetic intermediates and modular building blocks but traditionally suffers from poor selectivity and relatively complicated and/or harsh reaction conditions. We herein present the first visible-light-driven …

RAG-R1: Incentivizing the Search and Reasoning Capabilities of LLMs through Multi-query Parallelism

Jiaming Huang, Qintong Wu, Hongxuan Zhang, Chenyi Zhuang et autres

Large Language Models (LLMs), despite their remarkable capabilities, are prone to generating hallucinated or outdated content due to their static internal knowledge. While Retrieval-Augmented Generation (RAG) integrated with Reinforcement Learning (RL) offers a solution, these methods are fundamentally constrained by a single-query …
