The selective synthesis of heterocycles from readily available substrates and catalyzed by an abundant and environmental benign catalyst continues to be an attractive topic. In this communication, we report an interesting protocol for the synthesis of 2-aminofurans. Starting from 2-haloketones and tertiary amines, with abundant iron salt as the catalyst, various 2-aminofurans were produced in good yields. Control experiments were performed to understand the reaction pathway. Based on the identified reaction pathway, the substrates for this transformation can be extended from tertiary amines to enamines and even with better final yields. Finally, a formal three-component reaction can also be realized by forming the enamines in-situ from aldehydes and amines.

Bleach activators are herein disclosed having the stoichiometric formula: wherein R1, R2, R3, R4, R5 and R6 are each a radical selected from the group consisting of hydrogen, alkyl, aryl, alkylaryl, arylalkyl, phenyl, benzyl and mixtures thereof, or R5 and R6 together form a hydrogen carbon ring, n is an integer from 0 to 1, m is an integer from 1 to 2, and X is selected from mono- and polyvalent anions. These bleach activators are combined with a peroxygen compound capable of releasing hydrogen perioxide in an aqueous solution. The combination is especially effective in the removal of hydrophobic stains from fabrics.
