Using a commercially available, inexpensive, and abundant copper catalyst system, an efficient α-functionalization of nitroalkanes with propargyl bromides is now established. This mild and robust method is highly functional group tolerant and provides straightforward access to complex secondary and tertiary homopropargylic nitroalkanes. Moreover, the utility of these α-propargylated nitroalkanes is demonstrated through downstream functionalization to biologically relevant, five-membered N-heterocycles such as pyrroles and 2-pyrrolines.

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.
