報告題目：Rare Earth Catalyzed C-H Activation of Anisoles and Pyridines for Efficient Organic Synthesis and Polymer Functionalization
報告人：Masayoshi Nishiura
時間：12月29日上午9:50
地點：良鄉(xiāng)2號樓B座202
主講人信息：Masayoshi Nishiura教授在千葉大學Tsuneo Imamoto教授的指導下獲得碩士學位，2000年在此學校獲得博士學位。同年被聘為日本理化所特別研究員。2009年升為日本理化所高級研究員。他的研究主要針對用于有機合成的有機金屬催化劑和烯烴聚合。2009年榮獲日本理化所研究獎，2011年獲得日本有機合成化學進步獎，2013年獲得日本稀土學會青年科學家獎。
報告摘要： Pyridine and anisole moieties are among the most important structural motifs and exist widely in a large number of natural products, pharmaceuticals, ligands, and functional materials. Therefore, the development of efficient, atom-economical processes for the synthesis of pyridine and anisole-containing compounds through direct C-H functionalization has received intensive attention.
By the use of cationic half-sandwich rare-earth catalysts, an efficient and general protocol for the alkylation of various pyridine and anisole derivatives via C-H addition to olefins has been developed which provides an atom-economical method for the synthesis of alkylated pyridine and anisole derivatives. Furthermore, these rare earth alkyl complexes serve as catalysts for the polymerization of styrene via ortho-C-H alkylation of pyridines and anisoles as a chain transfer reaction, leading to the efficient synthesis of syndiotactic polystyrene bearing pyridyl and anisyl groups at chain-end.
