Retrieve references where substance's role is "Preparation"
Often best to look at oldest preparations first
Look for a preparation that meets your needs (e.g., scale, purity, convenience)
Some journals are specialize in synthesis (e.g., Organic Syntheses and Inorganic Syntheses)
Other “synthesis” journals include Synthesis and Synthetic Communications
Other chemistry journals such as the J. Am. Chem. Soc., Inorg. Chem. and J. Org. Chem.
