This paper presents an overview of the plenary lectures and some of the oral and poster presentations at the 4th International Congress on Oxidation Catalysis in Potsdam (Germany). The main topics were the partial oxidation of alkanes and the oxidation of olefins by H2O2. Considerable attention is given to the use of modern physical methods in the mechanistic studies of oxidation catalysis and in the studies of catalyst structures. 相似文献

In the presence of tetracyanoethylene, the reaction of two molecules of dihydrophosphinine oxide 2B followed an unexpected route to afford diphosphatricyclododecatrienes 4 instead of the corresponding Diels–Alder cycloadducts ( 3 ). Structures of the products ( 4 ) have been elucidated by a joint application of spectroscopy and quantum chemical calculations. © 2003 Wiley Periodicals, Inc.

Numerous substituted α‐aminophosphinates were synthesized by addition of alkyl and phenyl H‐phosphinates to aromatic imines and characterized. Modest diastereoselectivity was observed in the reaction. The size of the substituents exerts a small effect on the diastereoselectivity of P C bond formation. © 2003 Wiley Periodicals, Inc.
