Se ha llevado a cabo un analisis de la influencia de la calidad de la base utilizada para representar el sistema. Se ha llevado a cabo un analisis comparativo de los resultados teoricos obtenidos con los datos experimentales existentes mediante la utilizacion de un nivel de teoria suficientemente sofisticado que incluye las correcciones del error por superposicion de bases y de la energia vibracional del punto cero, asi como un tratamiento termodinamico estadistico. En lo que se refiere a la reaccion de staudinger se han estudiado los efectos de la base, de la correlacion electronica y del disolvente en el mecanismo de dicho proceso. Asimismo, se ha realizado un analisis de la influencia de distintos sustituyentes dadores y aceptores de electrones en el ceteno sobre la estereoquimica del proceso.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos
