The Meerwein-Ponndorf-Verley (MPV) reaction involves the catalysed transfer of hydrogen from an alcohol to a carbonyl compound and provides an effective method for synthesizing carbonyl compounds under very mild conditions. The method, which requires the use of a catalyst, is high selective as it leaves most reducible functional groups in the carbonyl reactant untouched. The classical MPV reaction is conducted in a Read More

The potassium anion possesses two valence electrons in its outer orbital. These two electrons might be transferred to an acceptor molecule simultaneously or stepwise. The stepwise mechanism had been stated till now experimentally only for the reaction of alkalide K-, K+(18-crown-6) with phenylacetylperoxide. A concept of this review was to ascertain if that mechanism has a more general character. Reactions of pota Read More

Transition metal-catalyzed reactions of methylenecyclopropanes (MCPs) 1 have been widely explored in this area of study over the past decades and some corresponding reviews have been reported. On the contrary, less attention has been paid for the Lewis acid or Bronsted acid-mediated reactions of MCPs. In the continuum of Lewis acid or Bronsted acid-mediated transformations of MCPs 1, we have found some novel tra Read More

Since our previous review article (Curr. Org. Chem. 2002, 6, 35), significant improvements and an array of 15N NMR applications in structural analysis have been published. This report aims to update coverage of improvements in methodology and various types of applications published over the period 2001 - 2005. Substantial progress in cryogenic probe technology and the commercial availability of cryoprobes have faci Read More
