1. INTRODUCTION The chemistry of three-membered ring heterocycles has played a
dominant role in the history of organic synthesis. 1 Countless classic and modern protocols …

Fatty epoxides are produced from the corresponding alkenes by oxidation in the presence of
peracids or other oxidants. The classic method is the Prilezhaev epoxidation in which …

The transition from petroleum to biorenewable sources of carbon to meet our energy and
chemical feedstock needs is difficult, in part because these sources are so different, with …

A Rh (III)-catalyzed annulation between salicylaldehydes and diazo compounds with
controllable chemoselectivity is described. AgNTf2 favored benzofurans via a tandem C–H …

Compared with the ripeness of olefin metathesis, exploration of the construction of carbon–
carbon double bonds through the catalytic carbonyl–olefin metathesis reaction remains …

The development of the highly active pincer-type rhodium catalyst 2 for the nucleophilic
Meinwald rearrangement of functionalised terminal epoxides into methyl ketones under mild …

We report the first example of a cobalt PCcarbeneP pincer complex (1) featuring a central
alkylidene carbon donor accessed through the dehydration of an alcoholic POP proligand …

Carbonyl-olefin metathesis is a potentially powerful yet underexplored reaction in organic
synthesis. In recent years, however, this situation has begun to change, most notably with …

Low‐valent nickel is shown to preferentially isomerize mono‐or disubstituted epoxides into
their corresponding aldehydes. Experiments with tetrasubstituted epoxides demonstrate that …

2-Nickelaoxetanes have been frequently invoked as reactive intermediates in catalytic
reactions of epoxides using nickel, but have never been isolated or experimentally observed …
