Formaldehyde → 2,2'-[ethane-1,2-diylbis(iminomethanediyl)]bis(4,6-di-tert-butylphenol)

Participants

Reaction Steps

A mixture of 2,4-di-tert-butylphenol (50 mmol), ethylenediamine (25 mmol) and 37% aqueous formaldehyde (50 mmol) was stirred in refluxing methanol for 2 h. The mixture was cooled to room temperature and the solid was filtered, and washed with methanol, yielding 13 in 45%. Spectroscopic data (not shown) supports formation of ligand precursor 13.
