Is the method used to generate the library of azo dyes an example of parallel or split synthesis? Explain your answer
Section 15.6 Excersize 9 in Experimental Organic Chemistry by Gilbert and Martin 6th edition
Homework Answers
The method used to generate the library of azo dyes is an example of parallel combinatorial synthesis .
During the production of azo dye substituted aniline is first converted to benzene diazinium salt and then it is treated with o/p directing aniline/phenol to form different class of azo dyes. Since the reactions are perfoemed in a sequential manner, parallel combinatorial synthesis is used to produce azo dye.

Question to answer from the lab: What aspect(s) of the approach taken is/are NOT especially green? What changes might be made to make the overall process greener? The Lab Experiment Summary Polyethylene glycols such as PEG-400 are currently of great interest to organic chemists, since their application as reaction solvents is very intriguing (1). PEG-400 is non-volatile and nonflammable in nature, and also possesses important properties such as recyclability, ease of work-up, thermal stability and economical cost. In addition, the...
