Provided is a salt, containing N-valent organic metal negative ion Mn- capable of forming metal atom of the bivalent-plus metal ion and Weng cationic capable of forming salt dyes with the organic metal negative ion. When the organic metal negative ion is the compound indicated in the formula (1) that meets specific requirements. The solvent performance of the salt in the organic solution is excellent.

A green, simple, and efficient protocol for the selective methylenation via CuCl2/oxygen-mediated C-H (sp3) oxidation and C-N cleavage using tetramethylethylenediamine (TMEDA) as a carbon source has been developed. The reactions were achieved in green solvent water under atmospheric conditions. The protocol exhibited a broad substrate scope including indoles, anilines, pyrroles and 1,3-dicarbonyls. Furthermore, two key intermediates of the reaction were successfully identified and the mechanism was explored. The Royal Society of Chemistry 2013.

Base-switched methylenation and formylation using tetramethylethylenediamine (TMEDA) as a carbon source have been achieved under mild conditions, catalyzed by CuCl2, with atmospheric oxygen as oxidant. Bisindolylmethanes, diphenylmethanes and 3-formylindoles were synthesized with excellent regioselectivity and good yield.
