The successful integration of large language models (LLMs) into laboratory workflows has demonstrated robust capabilities in natural processing, autonomous task execution, and collaborative problem-solving. This offers an exciting opportunity to realize the dream chemical research on demand. Here, we report a robotic AI chemist powered by hierarchical multiagent system, ChemAgents, based on-board Llama-3.1-70B LLM, capable executing complex, multistep experiments with minimal human intervention. It operates through Task Manager agent that interacts researchers coordinates four role-specific agents─Literature Reader, Experiment Designer, Computation Performer, Robot Operator─each leveraging one foundational resources: comprehensive Literature Database, extensive Protocol Library, versatile Model state-of-the-art Automated Lab. We demonstrate its versatility efficacy six experimental tasks varying complexity, ranging from straightforward synthesis characterization more complex exploration screening parameters, culminating discovery optimization functional materials. Additionally, introduce seventh task, where ChemAgents is deployed new chemistry lab environment autonomously perform photocatalytic organic reactions, highlighting ChemAgents's scalability adaptability. Our multiagent-driven showcases potential on-demand accelerate democratize access advanced across academic disciplines industries.

In this work, we present a dedicated, high-throughput reaction optimization platform allowing for the rapid evaluation of regiodivergent C–H borylation protocols while minimizing amount starting material required. The workflow was applied to diverse set fragment-like compounds, pharmaceuticals, and agrochemicals, its practicality demonstrated by successfully isolating 36 derivatives bioactive compounds. Leveraging informer library approach, provide comprehensive, side-by-side comparison catalytic methods, revealing insights into strengths, limitations, versatility each protocol. Surprising reactivity patterns, effectiveness ligand-free borylation, utility previously reported directed catalysts outside their expected substrate scope have been noticed. This study highlights potential dedicated platforms expand practical late-stage functionalization pharmaceutical agrochemical research.

Abstract Biomolecules labeled with radioisotopes of iodine and fluorine play a major role in science medicine, range applications including molecular imaging disease, as radiopharmaceuticals for therapy tools drug discovery. Due to the relative stability Csp2–halogen bonds, radioiodine radiofluorine labels are commonly incorporated into tracers via arene substitution. The wide availability aryl boron reagents has led their use development radioiodination radiofluorination methods, particularly using transition-metal complexes accelerated reactions. Here, we review transition-metal-mediated methods that have been developed radiohalogenation compounds. Applications these transformations preparation agents new technologies advance automated synthesis or high-throughput discovery also described. 1 Introduction 2 Radioiodination Using Aryl Boron Reagents 2.1 Copper-Mediated Reactions 3 Radiofluorination 3.1 Palladium, Nickel Silver Complexes 3.2 Copper 3.3 3.4 New Technology 4 Conclusions
