摘要： We demonstrate a step-economical and viable synthetic alternative to access a series of thieno[3,4- c ]pyrrole-4,6-dione (TPD)-based π-conjugated molecules through Pd-catalyzed direct C–H arylations. A comprehensive synthetic study including the screening of various kinds of palladium catalysts, ligands, and bases is reported. Under the optimum reaction conditions, TPD and its common derivatives underwent efficient and mild direct C–H arylations with a variety of functionalized bromoarenes. Functional groups such as ester, nitrile, ketone, aldehyde, and halide were well-tolerated, which substantially extended the reaction scope. We hope the reported method will provide materials scientists a relatively greener synthetic route to efficiently prepare TPD-containing π-functional materials. 出版日期： 2014-01-01 出處： RSC advances, 2014-01, Vol.4 (68), p.35868-35878 資源來源： Royal Society of Chemistry 識別號： ISSN: 2046-2069 識別號： EISSN: 2046-2069 識別號： DOI: 10.1039/C4RA05380J
