reduced Schiff base iron(III) complex(Ph−FeCl) afforded the highest yield of cyclohexanol and cyclohexanone(total yield up to 23.2 %). Notably, the Ph−FeCl complexcatalyzes the reaction via a heterogeneous approach, allowing the complex to be separated and recycled conveniently after the oxidation reaction. Besides, the Ph−FeCl catalyst can also be extended for the selective oxidation of other alkanes

solid state are grossly preserved in solution ( (1)H, (13)C, and circulardichroismspectra). Gas-phase geometry optimization and the electronic structures of [Re (V)O(L A (1))Cl 2], [Re (V)O(L A (2))Cl 2], and [Re (V)O(L B (2))Cl] have been investigated with the framework of density functional theory. The absorption and circulardichroismspectra of the complexes were also calculated applying time-dependent

Abstract Two tripodal vanadium complexes derived from modified l -phenylalanine were prepared and characterised. Both compounds were tested for their catalytic activity in the reductive coupling of benzaldehyde. Overall, the complexes are capable of catalysing the reductive coupling of benzaldehyde in the presence of metallic zinc as co-reductant and alkylammonium or alkylpyridinium acetate salts in
