The new azo compounds I(a-c) and II(a-c) were prepared by the reaction of I and II with three different aromatic amines, namely aniline, p-aminophenol and p-toluidine. The structures of these compounds were confirmed by CHN, FT-IR, 1H-NMR, 13C-NMR, mass spectrum and UV\/Vis spectroscopy.<\/jats:p>","DOI":"10.3390\/molecules15107498","type":"journal-article","created":{"date-parts":[[2010,10,25]],"date-time":"2010-10-25T11:34:23Z","timestamp":1288006463000},"page":"7498-7508","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":60,"title":["Synthesis of New Azo Compounds Based on N-(4-Hydroxypheneyl)maleimide and N-(4-Methylpheneyl)maleimide"],"prefix":"10.3390","volume":"15","author":[{"given":"Issam Ahmed","family":"Mohammed","sequence":"first","affiliation":[{"name":"School of Industrial Technology, Universiti Sains Malaysia, 11800 Penang, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asniza","family":"Mustapha","sequence":"additional","affiliation":[{"name":"School of Industrial Technology, Universiti Sains Malaysia, 11800 Penang, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2010,10,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"170","DOI":"10.3390\/90300170","article-title":"New imide 5-HT1A receptor ligands \u2013 modification of terminal fragment geometry","volume":"9","author":"Bojarski","year":"2004","journal-title":"Molecules"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"614","DOI":"10.1016\/j.ejmech.2006.12.003","article-title":"Novel and versatile methodology for synthesis of cyclic imides and evaluation of their cytotoxic, DNA binding, apoptotic inducing activities and molecular modeling study","volume":"42","author":"Alaa","year":"2007","journal-title":"Eur.
