In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 27349-66-2, name is 3-(Chloromethyl)pyridazine hydrochloride, introducing its new discovery. Recommanded Product: 3-(Chloromethyl)pyridazine hydrochloride

The new pyridazine containing iron complexes, [N,N,N?,N?-tetrakis(3-pyridazylmethyl)propylenediamine]iron(II)(PF6)2 (1) and [N,N?-bis(2-pyridazylmethyl)-N,N?-bis(2-pyridylmethyl)propylenediamine]iron(II) (PF6)2 (2) were synthesized and their reactivity towards protonation was compared to that of the analogous tetrapyridine complex [N,N,N?,N?-tetrakis(2-pyridylmethyl)propylenediamine]iron(II)(PF6)2 (3). The solution and solid-state structures were confirmed by NMR and X-ray crystallographic studies. For 1?3, the ligands bind in a hexadentate fashion giving similar octahedral structures with an N6 coordination environment. Across the series, the increasing number of pyridazines has only modest effects on the spectroscopic and electrochemical properties of the metal. Nevertheless, their reactivity towards protonation is drastically different. While 2 and 3 decompose in the presence of strong acids, 1 is able to be stably protonated as a result of cooperative second sphere interactions.

In the absence of molecular oxygen, various aromatic ketones such as acetophenone derivatives and diaryl ketones were photocatalytically hydrogenated on polycrystalline titanium dioxide (Degussa P25) under UV light irradiation (> 340 nm). The desired secondary alcohols were obtained with excellent chemical efficiency (almost 100% yields for 10 examples) by choosing ethanol as a sacrificial hole scavenger, which was oxidized into acetaldehyde.

Cycloaddition of pyridine N-imine with 6-alkyl-4-oxohex-5-ynoates followed by condensation with hydrazine provides concise access to pharmacologically active 6-(pyrazolo[1,5-a]pyridin-3-yl)pyridazinones. For the first time alkynyl heterocycles are also shown to be effective dipolarophiles for pyridine N-imine, and analogous compounds can be accessed directly in modest yields through the reaction of 6-(alkyn-1-yl)pyridazin-3-one derivatives.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Formula: C4H2Cl2N2. Introducing a new discovery about 141-30-0, Name is 3,6-Dichloropyridazine

The synthesis of a series of push-pull derivatives bearing triphenylamine electron-donating group, cyclopenta[c]thiophen-4,6-dione electron acceptor and various pi-linkers including (hetero)aromatic fragments is reported. All target chromophores with systematically varied pi-linker structure were further investigated by electrochemistry, absorption measurements, and EFISH experiments in conjunction with DFT calculations. Based on electrochemical and photophysical measurements, when a polarizable 2,5-thienylene moiety is embedded into the chromophore pi-backbone the highest intramolecular charge transfer (ICT) is observed. Benzene, pyrimidine, and pyridazine derivatives exhibit lower polarizability and extent of the ICT across these pi-linkers. The elongation of the pi-conjugated system via additional ethenylene linker results in a significant reduction of the HOMO-LUMO gap and an enhancement of the NLO response. Whereas it does not significantly influence electrochemical and linear optical properties, the orientation of the pyrimidine ring seems to be a key parameter on the mubeta value due to significant variation of the dipolar moment (mu) value. In 2a and 2c, pyrimidine is oriented to behave as an acceptor and thus generate dipolar molecule with mu above 5 D, whereas in 2b and 2d ground state dipole moment is significantly reduced. This study seems to indicate a high aromaticity of pyrimidine and pyridazine derivatives, close to the benzene analogues and significantly higher than thiophene analogues.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C4H2Cl2N2, you can also check out more blogs about141-30-0

Synthetic Route of 141-30-0, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 141-30-0, Name is 3,6-Dichloropyridazine, molecular formula is C4H2Cl2N2. In a Review，once mentioned of 141-30-0

In this contribution we provide an overview of the preparation and of the properties of different classes of luminescent dinuclear tricarbonyl rhenium(I) complexes of general formula [Re2(mu-X)2(CO)6(mu-1,2-diazine)] (X=halide, hydride, alkoxide, and thiolate). Their electrochemical and photophysical properties in solution are presented, as well as combined density functional (DFT) and time-dependent density functional (TDDFT) studies of their geometry, relative stability and electronic structure. The relationships between the structure and the emission properties of the complexes are discussed in detail, showing a modulation effect of the bridging ancillary ligands as well as of the diazine substituents on energy, lifetime and quantum yield of the emission. Photoluminescent quantum yields (Phi) up to 0.53 have been measured in fluid solution for the dichloro complexes containing diazines bearing alkyl groups in both the beta positions, designed to optimize all the parameters responsible for the radiative decay. The photophysical properties in the solid state are also briefly presented, showing in some cases an increase of the emission intensity, discussed in terms of restriction of intramolecular roto-vibrational motions. These properties, together with their good processability and high stability, allowed the successful use of some of these complexes as a phosphorescent dopant in OLEDs. The good performances of OLED devices prepared both by solution- and vacuum-processing are reported. The preliminary work exploring the potential of these complexes as luminescent labels for bioimaging is also presented.

The yields of the amination products depended on the structure of starting compounds. In the reactions of all the dichloroheteroarenes, selective substitution of only one chlorine atom took place, with the best yields being observed for 2,6-dichloropyrazine. In the reaction of 1,3-dichloroisoquinoline, the chlorine atom at position 1 was selectively substituted in up to 90% yield.
