Try ChemSpider

http://www.chemspider.com/

You can search structures with SMILES etc. Not as good as SciFinder but free.

You won't find a comprehensive free search engine for this kind of stuff.  Many large corporations synthesis and catalog thousands of compound each year which never see the light of day bu are logged in confidential files.
