Cyclohexane skeletal structure

Because of their suitable skeletal structure trans-CHD are applicable in the synthesis of compound classes of chemical, biological, and pharmaceutical interest. Regio- and stereoselective epoxidation of either one or two double bonds of 2, for example, opens up an approach to a group of naturally occurring cyclohexane epoxides which have attracted considerable attention because of their unusual structures, biogenesis, and biological activity [15].

As shown in Figure 21.10, cyclic hydrocarbons such as cyclohexane are represented by condensed, skeletal, and line structures. Line structures show only the carbon-carbon bonds with carbon atoms understood to be at each vertex of the structure. Hydrogen atoms are assumed to occupy the remaining bonding positions unless substituents are present. Hydrogens are also not shown in skeletal structures.

Ultrasonic agitation during leaching has recently been reported to increase the catalytic activity of skeletal nickel for the hydrogenation of benzene to cyclohexane, with the enhanced activity related to changes in the catalyst structure and surface species [47],...
