Introduction to Searching Chemical Literature with SciFinder® Scholar 2001

 

Instructions:

You can work in pairs on this project. However, try to go through the worksheet together with your partner and not with the entire section. It will be for your own benefit if you learn yourself how to locate relevant literature for a project. You will have to find references for your 'multi-step synthesis' report!

 

Start SciFinder Scholar 2001 by double clicking the SciFinder Scholar icon on the desktop. Acknowledge the license agreement. Then choose the first option (Chemical Substance or Reaction) on the next screen. You will use the chemical structure database first.

a) Draw the 1,2,3,4-tetraphenylnaphthalene molecule using the graphic

interface. Include all hydrogen atoms on the rings.

b) Choose Preview, and then choose Get Substances.

 

Q: How many compounds of relevance did the system find?

 

 

Pick the compound of interest by checking the box in the upper right hand corner. Choose Get References. Then choose Preparation, Properties and Spectral Data.

 

Q: How many references did the system find now?

 

 

Q: How many of them are really relevant to you?

 

 

Q: What is the CAS number (Registry #) of your compound?

 

 

Q: Which article(s) describe the preparation of the compound?

 

 

 

 

Q: What are the full names of the journals? (For example, is Org. Synth. an abbreviation for Organic Synthesis or Organic Syntheses?)

 

 

 

Q: Which of these journals are available in the SEL/Chemistry Collection?

View journal article via ChemPort -- click on computer icon

View journal article via California Digital Library's Periodical Titles database -- click on full-text icon; then click on Your Library to check for online access via CDL

Search ORION2, UCLA's online library catalog <http://orion2.library.ucla.edu> if necessary.

Q: What are their call numbers?

 

 

 

 

Q: Which of the articles is available online?

For example, Org. Synth.. <http://www.orgsyn.org> (in Science Learning Center, best viewed using Netscape as browser)

 

 

 

1)    Pick one of the electronically available journal articles and print out the first page of the article.

2)    Pick one of the SEL/Chemistry Collection available journal articles and photocopy the first page of the article.

3)    Cite the two journal articles according to the ACS style for chemistry journals

4)    Cite the two journal articles according to the ACS style for biochemistry journals

------------------------------------------------------------------------------------------------------------

ACS (American Chemical Society) journal article citation styles:

       What's the difference between the "Chemistry" and "Biochemistry" styles?

 

Chemistry (see Journal of the American Chemical Society

               http://pubs.acs.org/journals/jacsat/

 

Biochemistry (see Biochemistry

                           http://pubs.acs.org/journals/bichaw/

 

Journal article references typically include:

•      author's last name and first name or initials
•      title of the journal article
•      title of the journal in which the article appeared, usually abbreviated
•      date of the volume, including the year and sometimes the month
•      volume, and issue, of the journal in which the article appeared
•      pages on which the article appears

 

Example:

Wolkenberg, S. E.;and Su, A. I. Combinatorial Synthesis and Discovery of an

Antibiotic Compound. J. Chem. Educ. 2001, 78 (6) 784-785.

< http://jchemed.chem.wisc.edu/Journal/Issues/Current/abs784.html >

 

Citing sources, consult a style manual:

ACS style guide, a manual for authors and editors. 2^nd ed. Washington, DC.

American Chemical Society, 1997.

(SEL/Chem QD 8.5 A25 1997 Reserve)

------------------------------------------------------------------------------------------------------------

 

Go back to the Explore by Chemical Substance Screen. Choose Substance Identifier. Type in the CAS number that you got above including the dashes.

 

Q: How many references did you find?

 

 

 

Q: Where can you purchase the compound?

 

 

 

Q: Can you locate any IR, 1H-NMR or 13C-NMR data?

 

 

 

Q: If not, which sources would you consult to find this data?

 

 

 

Q: What is the crystal structure of the compound?

 

 

 

 

Q: Which other structural isomers of tetraphenylnaphthalene are known in the literature?

 

 

Reminder: You can download SciFinder Scholar at <http://dirac.chem.ucla.edu/scifind> and use it on your own computer if you dial in via Bruin Online. SciFinder Scholar is not currently available via UCLA's proxy server.

Alternative Structure Drawing Strategy (Use an existing registry number to "draw" a structure)

 

1.         Explore a chemical name with a Substance Identifier search.

2.         Click on the microscope icon.

3.         Highlight a Registry Number (CAS#) in a detailed reference.

4.         Select Copy from the Edit menu.

5.         Explore by Chemical Structure.

6.              Select Paste from the Edit menu.

 

The structure representing that CAS Registry Number is inserted into the drawing window. This structure may be modified, saved, or searched.
