Solvent-free synthesis of ferrocenylimines

The mixing of equimolar quantities of ferrocenylaldehydes and aromatic amines in a solvent-free environment provided excellent yields of ferrocenylimines. After mixing the aldehydes and amines, a melt formed which eventually solidified to the product. An analytically pure sample of the product was obtained by cold recrystallization. 2004 Elsevier Science B.V. All rights reserved.
