The sun protection factor (SPF rating, introduced in 1974) is a measure of the fraction of sunburn-producing UV rays that reach the skin. For example, “SPF 15” means that 1/15th of the burning radiation will reach the skin, assuming sunscreen is applied evenly at a thick dosage of 2 milligrams per square centimeter (mg/cm 2).
Steps: The amine attacks a carbonyl site on di-tert-butyl dicarbonate (Boc2O) resulting in tert-butyl carbonate leaving as a leaving group. Tert-butyl carbonate picks up the proton from the protonated amine.
