On September 4, 1990, Lai, J. S.; Wu, Rey F.; Lin, Ivan J. B.; Cheng, M. C.; Wang, Yu published an article.Product Details of 5034-06-0 The title of the article was Preparation of sulfur ylide complexes of platinum by phase transfer catalysis. And the article contained the following:

Various sulfur ylide complexes of Pt were prepared by the phase transfer catalysis (PTC). Thus, reaction of Pt(PR3)2Cl2 (R = Me, Ph) in CH2Cl2 with [S(O)(CH3)3]I under PTC/OH- conditions give complexes {Pt(PR3)2[(CH2)2S(O)(CH3)]}I, which contain a bidentate double sulfur ylide. With Pt(dppe)Cl2 [dppe = Ph2P(CH2)2PPh2] as starting material, a similar product was obtained. But when Pt(dppm)Cl2 [dppm = Ph2PCH2PPh2] was treated with [S(O)(CH3)3]Cl under PTC/OH- conditions, an unexpected product {Pt(PPh2CH3)(PPh2OH)[(CH2)2S(O)(CH3)]}Cl was obtained. This compound contains a bidentate double sulfur ylide and two unsym. phosphines resulting from the base hydrolysis of dppm. Compound {Pt(PPh3)2[(CH2)2S(O)(CH3)]}I, was subjected to an x-ray diffraction study. The experimental process involved the reaction of trimethyloxosulphonium chloride(cas: 5034-06-0).Product Details of 5034-06-0

Four mol. salts made from hexamethylenetetraminium and 2-chloro-4-nitrobenzoate have been synthesized and are reported, namely ammonium hexamethylenetetraminium bis(2-chloro-4-nitrobenzoate), NH4+·C6H13N4+·2C7H3ClNO4-, (I), hexamethylenetetraminium hydrogen bis(2-chloro-4-nitrobenzoate), 0.5C6H13N4+·C7H3.50ClNO4-, (II), hexamethylenetetraminium 2-chloro-4-nitrobenzoate, C6H13N4+·C7H3ClNO4-, (IIIa) and (IIIb). All four mol. salts show N+-H··O- hydrogen bonding. Salt (I) crystallized out with an NH4+ counter-ion which came from decomposition of 50% of the hexamethylenetetraminium cation in solution (II) shows an unusual asym. unit, with both a hexamethylenetetraminium cation and a partially deprotonated 2-chloro-4-nitrobenzoate anion. Salts (IIIa) and (IIIb) are polymorphs of each other. This work shows that hexamethylenetetramine only protonates once, even in the presence of excess acid. The experimental process involved the reaction of 2-Chloro-4-nitrobenzoic acid(cas: 99-60-5).Reference of 2-Chloro-4-nitrobenzoic acid

On September 18, 2015, Zhou, Xin; Yu, Changjiang; Feng, Zeya; Yu, Yang; Wang, Jun; Hao, Erhong; Wei, Yun; Mu, Xiaolong; Jiao, Lijuan published an article.Name: Methyl 6-chloro-6-oxohexanoate The title of the article was Highly Regioselective α-Chlorination of the BODIPY Chromophore with Copper(II) Chloride. And the article contained the following:

A general and efficient method for α-chlorination of 4,4′-difluoro-4-bora-3a,4a-diaza-s-indacenes (BODIPYs) was developed using CuCl2 as chlorination reagent. The reaction is characterized by complete 3/5-positions of BODIPY regioselectivity. This unusual highly regioselective α-halogenation of BODIPY is in sharp contrast to previously reported halogenation methods which preferred to occur first at the 2,6-positions of BODIPY. This approach provides a straightforward, facile, and economical route to 3- and/or 5-chloroBODIPYs with various meso-groups (H, alkyl, and aryl) and their derivatives The experimental process involved the reaction of Methyl 6-chloro-6-oxohexanoate(cas: 35444-44-1).Name: Methyl 6-chloro-6-oxohexanoate

On July 31, 2003, Jonnalagadda, S. B.; Shezi, M.; Pare, B. published an article.Synthetic Route of 4569-86-2 The title of the article was Uncatalyzed and ruthenium(III)-catalyzed reaction of acidic chlorite with methylene violet. And the article contained the following:

The kinetics and mechanism of the uncatalyzed and Ru(III)-catalyzed oxidation of methylene violet [3-amino-7-(diethylamino)-5-phenylphenazinium chloride] (MV) by acidic chlorite is reported. With excess concentrations of other reactants, both uncatalyzed and catalyzed reactions had pseudo-first-order kinetics with respect to MV. The uncatalyzed reaction had first-order dependence on chlorite and H+ concentrations, but the catalyzed reaction had first-order dependence on both chlorite and catalyst, and a fractional order with respect to [H+]. The rate coefficient of the uncatalyzed reaction is (5.72 ± 0.19) M-2 s-1, while the catalytic constant for the catalyzed reaction is (22.4 ± 0.3) × 103 M-1 s-1. Stoichiometry is dependent on the initial concentration of chlorite present. Consistent with the exptl. results, pertinent mechanisms are proposed. The proposed 15-step mechanism is simulated using literature; exptl. and estimated rate coefficients and the simulated plots agreed well with the exptl. curves. The experimental process involved the reaction of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride(cas: 4569-86-2).Synthetic Route of 4569-86-2

On February 28, 1998, Proevska, L. I.; Pojarlieff, I. G. published an article.Computed Properties of 4569-86-2 The title of the article was 1H NMR spectra and structure of safranines. Hindered rotation of the 3-dialkylamino group in 7-azo derivatives. And the article contained the following:

The 1H NMR spectra of safranine derivatives are reported. Semiempirical calculations indicate that the high shielding of the 4- and 6-proton adjacent to an amino or hydroxyl group (resonating between 5.5 and 6.0 ppm) is due to accumulation of neg. charge on the 4-and 6-C atoms, augmented by the magnetic anisotropy effect of the orthogonal 5-Ph ring. The ortho protons of the latter resonate up field to the meta and para protons. Hindered rotation of dialkylamino groups, altogether unexpected in view of the rather low barriers in similar anilines, is observed only in the azo derivatives AM1 suggests that this is due to destabilization of the transition state when an amino group is substituted for an azo group. The experimental process involved the reaction of 3-Amino-7-(diethylamino)-5-phenylphenazin-5-ium chloride(cas: 4569-86-2).Computed Properties of 4569-86-2
