incorporated into your prelab outline, which is based mainly on the lab text. This is a multistep synthesis. Great care must be used throughout to ensure obtaining a sufficient quantity of material to proceed to subsequent steps. A four step reaction wherein each step gives a 70% yield will result in a 24% overall yield (.7 x .7 x .7 x .7).

Multistep Synthesis When synthesizing complex organic molecules, it is common to have at least a dozen individual transformations whereby the product of one reaction is then used as the starting material for the next reaction. You will have an opportunity to do a multistep synthesis starting with inexpensive, readily available benzaldehyde.

advance of the lab. Find the journal article, "The Catalytic Oxidation of Benzoin to Benzil", J. Am. Chem. Soc. 1948, 70, 3666 and, using the procedure in that reference (small run), plan a synthesis of benzil starting with 0.0025 mol of benzoin, scaling down the quantities of all other reagents by the same factor.
