SciFinder and Reaxys are complementary databases, and it's recommended that you search both when searching for chemical reactions and preparations. While there is some overlap, there are significant differences between the two (strengths, journal coverage, time periods, indexing).
You can find more ebooks at UCSD through our catalog. Suggested searches include organic reaction* or organic synth*. The name reaction books (listed here with the most recently published title first) are arranged A-Z by reaction, and include mechanisms, examples and references to the journal literature.
Titles with a hyperlink can be browsed or searched online, but you'll need to go to our print copy to get the article.
