New Advances in Chemical Research, April 2021.The transformation of simple hydrocarbons into more complex has revolutionised modern synthetic chemistry. This type of reactivity has quickly become one of the cornerstones of modern catalysis .106-49-0, Name is p-Toluidine, SMILES is NC1=CC=C(C)C=C1, belongs to naphthyridine compound. In a document, author is Yang, Shu-Ting, introduce the new discover, Quality Control of p-Toluidine.
The direct reaction between 2,7-bis(2-pyridinyl)-1,8-naphthyridine (bpnp) and Pd(CH3COO)(2) in CF3COOH yields the new dinuclear palladium(II) complex [Pd-2(bpnp)(mu-OH)(CF3CO2)(2)](CF3CO2) (1). Similarly, substitution of Pd(CH3CN)(4)(BF4)(2) with bpnp in DMF gives [Pd-2(bpnp)(mu-OH)(DMF)(2)](BF4)(3) (2). Treatment of 1 or 2 with Cl- readily provide the chloro-substituted species [Pd(bpnp)(mu-OH)(Cl)(2)](+). All complexes were characterized by spectroscopic methods, and the structure of 2 was further confirmed by X-ray crystallography. Complex 1 is an efficient catalyst for the reduction of aromatic nitro compounds leading to the corresponding aniline derivatives under atmospheric pressure of hydrogen at 50 degrees C. The mechanistic pathway of the catalysis is investigated. From the reaction pathway, it is suggested that a facile condensation of nitroso and hydroxylamine intermediates is enabled by the dipalladium system and the desired transformation proceeds smoothly under mild reaction conditions to yield the reduced product.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 106-49-0, in my other articles. Quality Control of p-Toluidine.
