Organicsynthesis requires high-

purity starting materials to ensure successful reactions and to

reduce or eliminate unwanted sideproducts. The same is true for the catalysts;

activating, oxidizing, and reducing agents;and acids and bases that are used to trans-form organic molecules into desired reac-tion products. Aldrich is pleased to present

its line of high-purity inorganic andorganometallic reagents that have

significant contributions toorganic synthesis.

The use of activating agents and protecting groups in organic synthesis is necessary to preventunwanted side reactions from occurring when using other common reagents such as oxidizingor reducing agents. Another use is to prevent the undesired activation of a chemical function-ality when more than one such group exists in the reactant molecule. Aldrich has a wide selec-tion of activating reagents and protecting groups for use in your research.
