Gerard van Koten is Professor of Organic Chemistry and Catalysis at the Debye Institute of the Utrecht University (since 1986). He studied at the Utrecht University (Master of Science 1967). In 1967 he joined the Institute for Organic Chemistry, TNO as a permanent staff member and obtained his PhD (1974; Summa Cum Laude) from the Utrecht University (Prof. Dr. G.J.H. van der Kerk). In 1977 he moved to the University of Amsterdam (Inorganic Chemistry) where he was appointed to professor (personal chair) in Organometallic Chemistry. He retired 6 September 2007 and was appointed Emeritus Professor. February 2004 (to 2012) he has been appointed as Distinguished University Professor of the Utrecht University. In October 2007 he was appointed Part Time Distinguished Research Professor at the University of Cardiff (UK) (2007-2010).

His research interests comprise the study of fundamental processes in organometallic chemistry, the application of organometallic complexes as catalysts in homogeneous catalysis, in particular for fine-chemical synthesis, and as materials with special physicochemical properties (molecular wires and switches). He is well known for his ground breaking fundamental and applied research on XCX-pincer metal complexes. Recent developments involve the introduction of the XCX-pincer metal units in polypeptide chains, carbohydrates and in the active site of serine hydrolases. Furthermore systems are under development for cascade catalysis which is connected to his current interest in the development of sustainable (green) chemistry.

Presently he is member and chairman of the Academy Committee for Chemistry of the Royal Dutch Academy of Arts and Sciences (KNAW) and past-chairman of the Technical Committee of COST-Chemistry of the EU.

（通讯员 孙丹丹）12月4日，荷兰皇家科学院院士Gerard van Koten教授来我院开展学术交流，作题为“Donor-Acceptor features in NCN-Pincer Metal complexes”的学术报告。报告由陈宜鸿教授主持，高等研究院和相关院系众多师生参加现场交流。

Pincer类配体是一种能和金属形成螯合物的多齿配体，一个pincer配体至少要形成两个配位原子，又称钳状配体。报告中，Koten教授首先阐明了NCN钳状配体在有机锡化学中的应用，并对σ-有机金属的转化做了评述。报告围绕着NCN钳状配体金属络合物的给体-受体特征展开，从灵活性方面讲述了关于芳基金属-金属配合物的结合方式，紧接着，Koten教授对芳基钳状金属络合物的合成方面进行了讨论，并阐释了芳基金属钳状络合物的对位取代的后合成及应用，最后，Koten教授对芳基钳状金属络合物中金属-配体络合物的EW和ER特性进行了讲述。Koten教授指出，利用钳状金属络合物，可以实现络合物上σ键的多种类型的转化，并使得从单一的σ-芳基金属键上实现分子的多样性更容易实现。同时，这一类方法以已被越来越多学术界和工业的研究者关注并应用。

报告结束后，与会师生就报告相关问题与Koten教授展开了深入的讨论。
