Synthesis, characterization and molecular sensing behavior of [ZnCl2(η3-N,N,O-dpkbh)] (dpkbh=di-2-pyridyl ketone benzoyl hydrazone)

Copper(II) and zinc(II) complexes with 2-benzoylpyridine-methyl hydrazone

“…Metal complexes of hydrazones proved to have potential applications as catalysts [8], luminescent probes [9], and molecular sensors [10]. In addition, it has been recently shown that hydrazones such as pyridoxal isonicotinoyl hydrazone analogues are effective iron chelators in vivo and in vitro, and may be of value for the treatment of iron overload [11].…”

Synthesis, spectroscopic and X-ray crystallographic properties of manganese compounds of keto- and enol-coordinated di-2-pyridyl ketone benzoyl hydrazone (dpkbh). Reactions of [Mn(CO)5Br] with dpkbh

“…We are interested in the chemistry of di-2-pyridyl ketone derivatives (dpk-h) and have reported the synthesis, solution chemistry, and solid state structures of several dpk-h derivatives as well as their metal compounds [22][23][24][25][26][27][28][29][30]. Spectroscopic and electrochemical measurements on non-aqueous solutions of dpk-h and their metal compounds indicate sensitivity to changes in their surroundings to make them potentially useful as sensors for the detection of trace amounts of substrates including acids, bases, or group 12 metal chlorides [22][23][24][25]28]. In this report, reactions of dpkbh with [Mn(CO) 5 Br] that formed fac-[Mn I (CO) 3 (κ 2 -N py ,N im -dpkbh)Br]·H 2 O, [Mn II Br 2 (κ 3 -N py ,N im ,O-dpkbh)], and [Mn II (κ 3 -N py ,N im ,O-dpkbh-H) 2 ]·0.5H 2 O are described.…”

Suzuki–Miyaura cross-coupling reaction of aryl bromides catalyzed by palladium(II) pyridoxal hydrazone complexes

“…The most predominant coordination mode is tridentate, achieved through hydrazine nitrogen, phenolic oxygen and carbonyl oxygen atoms [30]. Metal complexes of hydrazones proved to have potential applications as catalysts [31], luminescent probes [32], and molecular sensors [33]. The availability of several publications in the literature clearly indicates the impact of the SuzukieMiyaura cross-coupling reaction in organic synthesis in the past two decades (1981e2001).…”
