So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Castello, Gianrico; Grandi, Francesco; Munari, Stelio researched the compound: 1-Iodo-2-methylbutane( cas:616-14-8 ).Safety of 1-Iodo-2-methylbutane.They published the article 《Gamma radiolysis of branched chain hydrocarbons. 2,3-Dimethylbutane》 about this compound( cas:616-14-8 ) in Radiation Research. Keywords: dimethylbutane radiolysis; iodine radical scavenger dimethylbutane; butane dimethyl radiolysis. We’ll tell you more about this compound (cas:616-14-8).

The γ-radiolysis of liquid 2,3-dimethylbutane at room temperature was investigated under vacuum. Iodine was used as a free radical scavenger and the formed alkyl iodides were analyzed by gas chromatog. with electron capture detector. Irradiations of frozen 2,3-dimethylbutane at 77°K were also performed. The fragmentation products and many of those having a number of C atoms higher than the parent were identified and measured. The formation of the identified heavy products is mainly due to recombination of radicals, as demonstrated by the comparison between their yields and those of alkyl iodides.

Safety of 1-Iodo-2-methylbutane. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 1-Iodo-2-methylbutane, is researched, Molecular C5H11I, CAS is 616-14-8, about Synthetic methods and reactions. 63. Pyridinium poly(hydrogen fluoride) (30% pyridine-70% hydrogen fluoride): a convenient reagent for organic fluorination reactions. Author is Olah, George A.; Welch, John T.; Vankar, Yashwant D.; Nojima, Mosatomo; Kerekes, Istvan; Olah, Judith A..

Pyridinium polyhydrogen fluoride (30% pyridine-70% HF) reagent, a stabilized, less-volatile form of HF, is a convenient and effective fluorinating agent. Fluorination, halofluorination, nitrofluorination, and hydrofluorination of olefins were achieved using the reagent. The in situ diazotization and subsequent fluorinative dediazonization of α-amino acids, aminoarenes, and carbamates yielded α-fluorocarboxylic acids, aryl fluorides, and fluoroformates, resp. Geminal dihalides and α-halo ketones were treated with HgO in pyridinium polyhydrogen fluoride to form geminal difluorides and α-fluoro ketones. Solutions of alkali halides in pyridinium polyhydrogen fluoride were also effective halogenating agents for aminoarenes, via in situ diazotization and subsequent nucleophilic dediazonization by the corresponding halides, as well as for alcs., via SN2 displacement reactions. Diazo ketones and diazoalkanes also reacted smoothly with halide ions in pyridinium polyhydrogen fluoride solution to give the corresponding geminally halofluorinated compounds Proper precautions must be observed in using pyridinium polyhydrogen fluoride.

The first total syntheses of verrucines A and B and anacine (revised structure) were accomplished on Sasrin resin. This work confirmed the structure of verrucine A and unambiguously showed verrucine B to be a derivative of D-phenylalanine and L-glutamine. The study also proved that anacine and its epimer are quinazoline alkaloids, not benzodiazepines as originally proposed. 1-Hydroxyverrucine B, derived from air oxidization of verrucine B, was also isolated and characterized.
