For more complete results, search multiple databases. The two main resources are Beilstein and SciFinder Scholar (from Chemical Abstracts).
Reaction searching in Scholar retrieves mainly novel reactions, rather than every occurrence. For exhaustive retrieval of preparations of specific substances, use a structure preparation search strategy instead. Covers the chemical literature thoroughly, including patent literature. Please remember to logoff when finished. There are a very limited number of simultaneous users allowed at one time for the University of Michigan subscription.
Covers the largest number of structure/reaction searchable chemical reactions, but a smaller number of journal sources (almost no patent coverage). Good first choice when you are looking for very specific reaction examples. Also, there are no limits on simultaneous usage for the University of Michiga campus. Please remember to logoff when finished.
