carbodiimidoester with hydrazines. Formation of [1,2,4]triazines of type 7 was not observed. Simultaneously with the formation of 2, an interesting transformation was also observed to afford a novel imidazolone derivative (3) containing two ferrocenyl groups. The structures of the products were determined by IR, 1H- and 13C-NMR spectroscopy (including 2D-COSY, DEPT, 2D-HMQC, and 2D-HMBC measurements), and in the case
