This contribution was performed via the condensation of phenylhydroxylamine with several aryl aldehydes, in the absence of both catalyst and solvent, and using microwave irradiation as the activating reaction mode. In addition, good yields of the products were achieved in a short time. It is also worth noting that the work-up procedure is simple and the products do not require further purification. Finally, an interesting comparison without the use of microwave irradiation is also discussed.<\/jats:p>","DOI":"10.3390\/ijms11062576","type":"journal-article","created":{"date-parts":[[2010,6,22]],"date-time":"2010-06-22T11:07:11Z","timestamp":1277204831000},"page":"2576-2583","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Eco-Contribution for the Production of N-Arylnitrones: Solvent-Free and Assisted by Microwaves"],"prefix":"10.3390","volume":"11","author":[{"given":"Leonor","family":"Reyes","sequence":"first","affiliation":[{"name":"Departamento de Ciencias Qu\u00edmicas, Facultad de Estudios Superiores Cuautitl\u00e1n-UNAM, Estado de M\u00e9xico, 54754, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra","family":"Corona","sequence":"additional","affiliation":[{"name":"Departamento de Ciencias Qu\u00edmicas, Facultad de Estudios Superiores Cuautitl\u00e1n-UNAM, Estado de M\u00e9xico, 54754, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel","family":"Arroyo","sequence":"additional","affiliation":[{"name":"Departamento de Ciencias Qu\u00edmicas, Facultad de Estudios Superiores Cuautitl\u00e1n-UNAM, Estado de M\u00e9xico, 54754, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francisco","family":"Delgado","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica Org\u00e1nica, Escuela Nacional de Ciencia Biol\u00f3gicas-IPN, M\u00e9xico D.F., 11340, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ren\u00e9","family":"Miranda","sequence":"additional","affiliation":[{"name":"Departamento de Ciencias Qu\u00edmicas, Facultad de Estudios Superiores Cuautitl\u00e1n-UNAM, Estado de M\u00e9xico, 54754, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2010,6,22]]},"reference":[{"key":"ref_1","first-page":"153","article-title":"Microwave-assisted, one-pot multicomponent synthesis of highly substituted pyridines of medicinal utility using KF\/alumina","volume":"XIII","author":"Nand","year":"2009","journal-title":"ARKIVOC"},{"key":"ref_2","unstructured":"Torssell, KBG (1988).
