Organic Chemistry: An Introduction Emphasizing Biological ...
When we do such an experiment, we discover that cyclopropane releases 500
kcal/mol in the course of burning (this is called its "heat of combustion," AHcomb).
So what? Is this how uncomfortable cyclopropane is? No, not at all: after all, other
...

Complex Catalytic Processes
5.2 THE HYDROGENATION OF CYCLOPROPANE The metal-catalysed
hydrogenation of cyclopropane has been extensively studied. Although the
reaction was first reported in 1907 [242], it was not until some 50 years later that
the first ...
