Visualising molecules in 3D is hard. Fortunately, chemists use quite a few of the important stereochemical concepts and terms to describe the shapes of more 2D molecules, like alkenes. So, even if you really came to this book to learn about chirality and conformations in molecules with sp3 carbon atoms, we suggest you venture first into the sp2 world ...

This chapter considers the relations between alkanes, alkenes, and alkynes, noting that the first general characteristic of alkenes and alkynes is their tendency to be attacked by electrophiles. It mentions that the spherical s orbital of C may be regarded as near to the positive nucleus, while the pear-shaped p orbital may be considered as farther ...

Highly Efficient Alkene-Alkene and Arene-Alkene Coupling Reactions with Vicinal Dibromides
Synlett, 1990Palladium-catalyzed twofold coupling reactions of 1,2-dibromocycloalkenes 4, 7 with alkenes 2 give high yields of (E,Z,E)-1.3,5-hexatrienes 5, 8 which thermally cyclize to ringannulated 1,3-cyclohexadienes 6, 9. Two-, three- and fourfold Heck type coupling reactions were also achieved with vicinal di-13, tri- 16, and tetrabromobenzene 18 under ...

Publisher Summary The method for asymmetric epoxidation of alicyclic alcohols is known as Sharpless. The success of this method initiated much research into other techniques of asymmetric oxidation of alkenes in general and this chapter considers the progress in the area for the last six years.
