Designing a Synthesis

Organic synthesis is a branch of chemical synthesis that involves the planned construction of organic compounds/molecules from smaller units that possess functional groups. Friedrich Wöhler was the first scientist who designed the synthesis of an organic compound, urea from inorganic starting materials silver cyanate with ammonium chloride via a simple, one-step synthesis.

The overall reactants in Equation 8-3 are R and ucts are Nu-R and L. The carbocation (R*) that appears in the reaction mecha- nism (Equation 8-2) is the only intermediate. In the S1 mechanism shown here, (a) identify each species as an overall reactant, overall product, or intermediate, then (b) sum the steps to yield the overall reaction. :Br: + Br: 11 :I: + One reason to distinguish intermediates from overall reactants and products is to know which species in the mechanism can be isolated.
