New research progress on 496-72-0 in 2021. 496-72-0, Name is 3,4-Diaminotoluene, molecular formula is C7H10N2, Category: naphthyridines, SMILES is CC1=CC=C(N)C(N)=C1 belongs to naphthyridine compound, is a common compound. In a patnet, author is Majumdar, Moumita, once mentioned the new application about 496-72-0.
Reaction of cis-[Mo-2(OAc)(2)(CH3CN)(6)][BF4](2) with NP-Et, Me (2-ethyl-3-methyl-1,8-naphthyridine) in acetonitrile provides trans-[Mo-2(NP-Et, Me)(2)(OAc)(2)(CH3CN)][BF4](2) (1). Partial protonation of 1 by HBF4 center dot Et2O in acetonitrile leads to trans-[Mo-2(NP-Et, Me)(2)(OAc)(CH3CN)(3)][BF4](3) (2). In both compounds, NP-R ligands are arranged in a head-to-head (HH) fashion leaving one of the axial sites vacant. Substitution of acetonitriles by NP-Me (3-methyl-1,8-naphthyridine) in trans-[Mo-2(NP-tz)(2)(OAc)(CH3CN)(2)][BF4](3) provides trans-[Mo2(NP-tz) 2(OAc)(NP-Me)][BF4] 3 (3) with retention of configuration. Fully solvated dimolybdenum( II) compound reacts with NP-NH2 to provide [Mo-2(NP-NH2)(2)(NP-NH)(CH3CN)(2)][BF4](3) (4) in which the NP-NH2 ligands are trans and arranged in a HH fashion. The deprotonated ligand (NP-NH ) binds the dimetal unit utilizing naphthyridine nitrogen and amido nitrogen. Treatment of [Mo-2(NP-tz) (2)(CH3CN)(4)][CF3SO3](4) with bpym (2,2′-bipyrimidine) followed by crystallization in air provided an oxo complex [Mo-2(NP-tz)(2)(mu(2)-O)(2)(bpym)(2)][CF3SO3](4) (5). Compounds 1-5 have been characterized by a variety of spectroscopic techniques and by X-ray crystallography. The reactivity pattern is rationalized based on ligand labilities and thermodynamic stabilities. (C) 2010 Elsevier B. V. All rights reserved.
