Reactions of 2‐ferrocenylmethylidene‐1,3‐diketones ( 1a , 1b , 1c ) with methylhydrazine afford mainly insertion products (∼40–58%), viz ., 1‐( N ′‐acyl‐ N ′‐methylhydrazino)‐1‐ferrocenyl‐2‐acylethanes ( 7a , 7b , 7c , 7d ), together with lesser amounts of pyrazoles ( 8a , 8b ) and dihydropyrazoles ( 9a , 9b ).
