Abstract

LOS COMPUESTOS DE CETONA SON ELABORADOS DE TAL FORMA QUE PRIMERO SE EFECTUA UNA CONDENSACION, EN DONDE SE FORMA UN ENOLATO, Y A CONTINUACION SE GENERA UNA PROTONIZACION EN LOS COMPUESTOS DE CETONA LIBRES. DE ACUERDO CON LA INVENCION SE REALIZAN AMBAS REACCIONES DE FORMA ELECTRODIALITICA EN UN PASO DE PROCEDIMIENTO.
