X‐ray structurally characterized Mo (VI), Fe (III) and Cu (II) complexes of amide‐imine conjugate: (bio)catalytic and histidine recognition studies.

An amide‐imine conjugate, (E)‐N′‐((2‐hydroxybenzen‐1‐yl) methylene)‐4‐methylbenzohydrazide (H2LPTASAL), derived from 4‐methyl‐benzoic acid hydrazide (PTA) and 2‐hydroxybenzaldehyde is used to prepare Mo (VI), Cu (II) and Fe (III) complexes. The X‐ray structurally characterized complexes have been explored as catalyst for amine assisted asymmetric ring opening (ARO) of epoxide, carbon‐heteroatom cross‐coupling and ethyl benzene oxidation. In addition, their catecholase like activities have thoroughly been investigated. Moreover, the Cu (II) complex selectively recognizes histidine by fluorescence spectroscopy. [ABSTRACT FROM AUTHOR]
