Charge transfer complexes of bromine iodide and chlorine iodide with azoles, Name: Pyridine Iodochloride complex, the publication is Zhurnal Obshchei Khimii (1976), 46(11), 2576-9, database is CAplus.

UV and dipole moment data were given for complexes of imidazoles, pyrazoles, thiazoles, oxazoles, and isoxazoles with ClI and BrI. The stability of the BrI complexes was lower than that of the ClI complexes, but both types were more stable than the analogous I2 complexes. The change of the dipole moment on complexation, the degree of charge transfer, and the stability constant all increased as the basicity of the azole increased.

Kadiyala, Raghu Ram published the artcileComputed CH acidity of biaryl compounds and their deprotonative metalation by using a mixed lithium/zinc-TMP base, Synthetic Route of 1331850-50-0, the publication is Chemistry – A European Journal (2013), 19(24), 7944-7960, database is CAplus and MEDLINE.

A number of substituted biaryls, arylpyridines, arylpyrimidines and arylquinolines was prepared by coupling reactions; deprotonation-iodination with a mixed lithium/zinc-TMP base gives the corresponding iodides. The obtained exptl. results on acidity are compared with calculated values of Gibbs energies of deprotonation at different positions of the considered biaryl and arylheterocyclic systems. With the aim of synthesizing biaryl compounds, several aromatic iodides were prepared by the deprotonative metalation of methoxybenzenes, 3-substituted naphthalenes, isoquinoline, and methoxypyridines by using a mixed lithium/zinc-TMP (TMP = 2,2,6,6-tetramethylpiperidino) base and subsequent iodolysis. The halides thus obtained, as well as com. compounds, were cross-coupled under palladium catalysis (e.g., Suzuki coupling with 2,4-dimethoxy-5-pyrimidylboronic acid) to afford various representative biaryl compounds Deprotometalation of the latter compounds was performed by using the lithium/zinc-TMP base and evaluated by subsequent iodolysis. The outcome of these reactions has been discussed in light of the CH acidities of these substrates, as determined in THF solution by using the DFT B3LYP method. Except for in the presence of decidedly lower pK_a values, the regioselectivities of the deprotometalation reactions tend to be governed by nearby coordinating atoms rather than by site acidities. In particular, azine and diazine nitrogen atoms have been shown to be efficient in inducing the reactions with the lithium/zinc-TMP base at adjacent sites (e.g., by using 1-(2-methoxyphenyl)isoquinoline, 4-(2,5-dimethoxyphenyl)-3-methoxypyridine, or 5-(2,5-dimethoxyphenyl)-2,4-dimethoxypyrimidine as the substrate), a behavior that has already been observed upon treatment with lithium amides under kinetic conditions. Finally, the iodinated biaryl derivatives were involved in palladium-catalyzed reactions.

Chen, Linfeng published the artcileNovel Colorimetric Method for Simultaneous Detection and Identification of Multimetal Ions in Water: Sensitivity, Selectivity, and Recognition Mechanism, Quality Control of 606-55-3, the publication is ACS Omega (2019), 4(3), 5915-5922, database is CAplus and MEDLINE.

Accurate recognition and speciation anal. of heavy metal ions in complex hydrol. environments is always a serious challenge. Here, we propose a small mol. based ultrasensitive colorimetric detection strategy, and apply to the accurate detection of Fe²⁺, Fe³⁺, Co²⁺ and Hg²⁺ in groundwater through the specific recognition of multiple ligands for different metals. The detection limits for Hg²⁺, Co²⁺, Fe²⁺ and Fe³⁺ are calculated as 6.51, 0.34, 0.49 and 1.01 ppb, resp., which are far below the drinking water standards and superior to most of the reported colorimetric sensors. The speciation anal. of Fe²⁺/Fe³⁺ also was realized by a 1-step method without complex pretreatment. The speciation and concentration of Fe²⁺ and Fe³⁺ in actual water samples can be accurately identified and monitored. For a visual on-site detection, we developed a simple test strip and applied to visual monitoring of 4 metals with the detection limit estimated by the naked eye as low as ppb-levels. This colorimetric method realizes the rapid, sensitive and portable multiple metal recognition and Fe²⁺/Fe³⁺ speciation anal., displaying great potential for on-site rapid water quality anal.

An inexpensive and new triphenylphosphine-based palladacycle has been developed as a pre-catalyst, leading to highly effective Stille cross-coupling reactions in water under mild reaction conditions. Only 500-1000 ppm of Pd suffices for couplings involving a variety of aryl/heteroaryl halides with aryl/hetaryl stannanes. Several drug intermediates can be prepared using this catalyst in aqueous nanoreactors formed by 2 wt % Brij-30 in water.

Several low-molar-mass alkyl iodides were studied as initiating dormant species in living radical polymerization with organic catalysts. Primary, secondary, and tertiary alkyl iodides with different stabilizing groups (ester, Ph, and cyano groups) were systematically studied for the rational design of initiating alkyl iodides. The activation rate constants of these alkyl iodides were exptl. determined for quant. comparison. These alkyl iodides were used in the polymerizations of Me methacrylate and Bu acrylate to examine their initiation ability in these polymerizations A telechelic polymer was prepared using an alkyl iodide with a functional group. Alkyl iodides with multi-initiating sites were also studied.

Herein, the authors disclose a general and efficient method for the synthesis of Sb-aryl and Sb-alkyl stibines by the Ni-catalyzed cross-coupling of halostibines with organic halides. The synthesized Sb-aryl stibines couple with aryl halides to give biaryls efficiently via Pd catalysis. Sequential reactions of stibines with polyhalogenated arenes bearing active C-I/C-Br sites and inactive C-Cl sites successfully proceeded, giving a variety of complex mols. with good site selectivity. Drugs such as diflunisal and fenbufen, as well as a fenofibrate derivative, were synthesized on gram scales in good yields, together with the high recovery of chlorostibine. Also, catalytic mechanisms are proposed based on the results of control experiments

A variety of cyclic sulfonamides and sulfinamides could be selectively synthesized under Pd catalysis using haloarenes bearing amino groups and a sulfur dioxide (SO₂) surrogate. The amount of base was key in determining the selectivity. Mechanistic studies revealed that sulfinamides were initially formed via an unprecedented formal insertion of sulfur monoxide and were oxidized to sulfonamides in the presence of an iodide ion and DMSO.
