Conditions have been developed for the reductive cross-coupling of 3-bromo-2,1-borazaronaphthalenes with primary and secondary alkyl iodides. This method allows direct alkylation of azaborine cores, providing efficient access to functionalized isosteres of naphthalene derivatives.

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.category: Tetrahydrofurans, you can also check out more blogs about121138-01-0

Application of 121138-01-0, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 121138-01-0, 3-Iodotetrahydrofuran, introducing its new discovery.

The kinetics of the transfer of X+ from the bromonium and iodonium ions of adamantylideneadamantane (1-Br+ and 1-I+) to some 1,omega-alkenols and alkenoic acids in ClCH2CH2Cl at 25C was investigated. In all cases, the expected products of halocyclization were observed. For the iodonium ion transfer the reaction kinetics are second order overall, first order in both 1-I+ and acceptor olefin. Transfer of the bromonium ion from 1-Br+ to these acceptor olefins exhibits different kinetic characteristics. In most cases, the rate of the Br+ transfer is subject to strong retardation in the presence of added parent olefin (Ad=Ad), suggestive of a common species rate depression. In some cases, such as 4-penten-1-ol (2b) and 4-pentenoic acid (4b), the reaction can be completely suppressed at high [Ad=Ad]. In other cases, such as 3-buten-1-ol (2a), 5-hexen-1-ol (2c), cyclohexene, 4-(hydroxymethyl)cyclohexene (3), and 5-endo-carboxynorbornene (5), added Ad=Ad does not suppress the reaction completely. In the cases of the 1,omega-alkenols, the reactions appear to exhibit kinetic terms that are greater than first order in alkenol. In these cases, alcohols such as 1-pentanol also accelerate the reaction, pointing to the involvement of the hydroxyl group of the second alkenol as a catalytic species. A unifying mechanism consistent with the data that involves two reversibly formed intermediates is presented.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application of 121138-01-0. In my other articles, you can also check out more blogs about 121138-01-0

Complementary chemistry: A one-pot method for the site-selective alkylation of arenes controlled by steric effects is reported. The process occurs through Ir-catalyzed C-H borylation, followed by Pd- or Ni-catalyzed coupling with alkyl electrophiles. This selectivity complements that of the typical Friedel-Crafts alkylation; meta-selective alkylation of a broad range of arenes with various electronic properties and functional groups occurs in good yield with high site selectivity.

(-3-ketotetrahydrofuran-2-yl) ethanal derivatives and a method for their preparation

Compounds having utility in medicine in countering cellular malfunction e.g. in conditions embraced by the general term “cancer”, which compounds normally exist us a keto-enol tautomeric pair, the racetalc keto form of which is rapresented by formula (Ia), wherein R is a hydrogen, lower alkyl, acyl, or another functional group of up to 6 carbons including at least one hetero atom, which atom may be directly bonded to the beta-carbon, which compound may be in the acylic form shown or in a cyclic form as equilibrium keto-enol tautomer derivatives and anomeric forms thereof, including enantiomers when R is hydrogen and diastereoisomers when R is another group. A method of obtaining such a compound comprises selecting an appropriate dihydrofuran having a protected primary alcohol side chain in the 2-position, subjecting the said protected alcohol side chain-substituted dihydrofuran to oxidation using a chromium-based reagent to yield the corresponding acid, subjecting said acid to iodolaetonisation conditions to yield the cis,cis,trans-trisubstituted iodo-lactone which upon displacement of the iodine provides the cis,cis,cis-tri-substituted hydroxylacetone which is capable of being reduced to obtain a lactol which is in equilibrium with the corresponding open chain aldehyde.
