New azaalkyl or azacrown ferrocenyl compounds containing a C 5 H 4 COCC‐ linkage are accessible from mono‐ or diacetylferrocene upon treatment with the appropriate aldehydes (CHOC 6 H 4 ‐ p ‐R, R = NEt 2 , N‐aza‐15‐crown‐5). Preliminary results concerning the electrochemical behaviour of complexes [(C 5 H 5 )Fe(C 5 H 4 COCH=CHC 6 H 4 NEt 2 )] ( 3a ), [Fe(C 5 H 4 COCH=CHC 6 H 4 NEt 2 ) 2 ] ( 5a ), the novel ferrocenophane [Fe(C 5 H 4 COCH 2 ) 2 CHC 6 H 4 NEt 2 ] ( 6a ) and its protonated species [Fe(C 5 H 4 COCH 2 ) 2 CHC 6 H 4 NHEt 2 ][BF 4 ] ( 7a ), are reported. The ferrocenyl ligand 5a is a rare example of a molecule which is both electroactive and fluorescent.
