Siegfried Blechert (born 1 May 1946 in Aalborg, Denmark) is a German chemist.
Professor Siegfried Blechert studied chemistry at the University of Hannover, Germany and completed his PhD under the supervision of Professor Ekkehard Winterfeldt in 1974. After a research stay with Professor Pierre Potier in Gif-sur-Yvette, France, in 1981, he finished his habilitation at the University of Hannover in 1982 and there became lecturer in organic chemistry. In 1986 he took up a professorship at the University of Bonn. In
1st generation Hoveyda–Grubbs catalyst was reported in 1999 by Amir H. Hoveyda's group, and in the following year, the second-generation Hoveyda–Grubbs catalyst was described in nearly simultaneous publications by the Blechert and Hoveyda laboratories. Siegfried Blechert's name is not commonly included in the eponymous catalyst name. The Hoveyda–Grubbs catalysts, while more expensive and slower to initiate than the Grubbs catalyst from which they are derived, are popular because of their improved stability. By changing the steric and electronic properties of the chelate,
