Ketone-derived Peroxides. Part I. Synthetic Methods.

Study of the reactivity of peroxides derivable from ketones by reaction with hydrogen peroxide has required reexamination of preparative methods.Conditions for obtaining five known peroxides from cyclohexanone and the new 1-(1-hydroxycyclohexyldioxy)-1-(1-hydroperoxycyclohexyldioxy)cyclohexane (10) are carefully defined.An improved general method for obtaining cyclic diperoxides (3,3,6,6-tetrasubstituted 1,2,4,5-tetraoxans) (6) has been developed and used to obtain new diperoxides from dibenzyl ketone, di-(4-methylbenzyl) ketone and 2,2-dimethylcyclohexanone whereas indan-2-one and 5,7-dihydro-6H-dibenzocyclohepten-6-one yield the corresponding triperoxides (1,2,4,5,7,8-hexoxonans) (7) and 1,5-diphenylpentan-3-one yields bis-(1-hydroperoxy-1-phenethyl-3-phenylpropyl) peroxide (5k).Ozonolysis of appropriate alkenes has been used to obtain new cyclic diperoxides formally related to 4′-methylacetophenone, propiophenone and deoxybenzoin.

Chemoselective transfer hydrogenation of Alpha,Beta-unsaturated carbonyls catalyzed by a reusable supported Pd nanoparticles on biomass-derived carbon

We herein report highly chemoselective transfer hydrogenation of alpha,beta-unsaturated carbonyl compounds to saturated carbonyls with formic acid as a hydrogen donor over a stable and recyclable heterogeneous Pd nanoparticles (NPs) on N,O-dual doped hierarchical porous biomass-derived carbon. The synergistic effect between Pd NPs and incorporated heteroatoms on carbon plays a critical role on promoting the reaction efficiency. A series of alpha,beta-aromatic and aliphatic unsaturated carbonyl compounds was selectively reduced to their corresponding saturated carbonyls in up to 97% isolated yields with good tolerance of various functional groups. In addition, the catalyst can be successively reused for at least 6 times without significant loss in reaction efficiency.

The double Michael reactions between benzofuran-3-one or 1-indone and symmetric dienones in the presence of catalytic ionic liquids were successfully developed and spiro[benzofuran-2,1?-cyclohexane]-3-one or spiro[cyclohexane-1,2?-indene]-1?,4(3?H)-dione derivatives containing a spiro quaternary stereogenic center, which widely exist in biologically active products and building blocks in organic synthesis, were obtained in excellent yields (up to 99%). This catalytic system was also extended to the double Michael reaction of less reactive 1-indone and the desired products were also obtained in 31%-62% yields. The catalytic system was highly active and efficient for a broad of substrates under mild conditions.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Formula: C17H14O, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 538-58-9, Name is 1,5-Diphenylpenta-1,4-dien-3-one, molecular formula is C17H14O

Rate and mechanism of the reaction of (E)-PhCH=CH-CH(Ph)-OAc with palladium(0) complexes in allylic substitutions

The reaction of (E)-1,3-diphenyl-3-acetoxyprop-1-ene, PhCH=CH-CH(Ph)-OAc, with palladium(0) complexes Pd0L2, generated from Pd 0(PPh3)4 or Pd0(dba)2 + 2L (L = PPh3 or L2 = dppb), gives cationic [(eta3-PhCH-CH-CHPh)PdL2]+ complexes with AcO- as the counteranion in DMF. It is established that this reaction proceeds through two successive equilibria via neutral intermediate complexes (eta2-PhCH=CH-CH(Ph)-OAc)Pd0L2, characterized from the kinetics and by UV and 31P NMR spectroscopy. The rate constants and equilibrium constants of the successive steps have been determined in DMF. They depend on the ligand and the Pd0 precursor. In all cases, for the concentration range investigated here, the complexation is considerably faster than the ionization, which is the rate-determining step of the overall process. Under similar experimental conditions, the formation of the cationic complex [(eta3-PhCH-CH-CHPh)Pd(dppb)]+ is considerably slower than the formation of the complex [(eta3- CH2-CH-CH2)Pd(dppb)]+ in DMF.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C17H14O, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 538-58-9, in my other articles.

Sodium-iodoxybenzoate mediated highly chemoselective aziridination of olefins

Herein we utilized, for the first time, sodium 2-iodoxybenzoate as a highly specific oxidant for PhthNH2 to create a highly chemoselective aziridination reagent. This method efficiently effects aziridination of electron-rich, electron-deficient, allylic alcohol and alkenyl bromide C=C bonds in good to excellent yields. Inter and intramolecular chemoselectivity was demonstrated between electron-rich and electron-deficient alkenes by using this efficient and metal free protocol.

Cellulose sulfonic acid as a green, efficient, and reusable catalyst for Nazarov cyclization of unactivated dienones and pyrazoline synthesis

A high yielding, eco-friendly and simple procedure for the synthesis of five membered carbo- and heterocycles through cellulose sulfonic acid (CSA) mediated electrocyclization processes has been developed. Cellulose sulfonic acid (CSA) not only was able to induce the cyclization of “unactivated” dienones generating cyclopentenoids; it was also able to trigger the cyclization of alpha,beta-unsaturated hydrazones giving rise to pyrazolines in excellent yields under green reaction conditions. The ease of catalyst recovery and reusability, short reaction time, simple experimental and work-up procedure; compared to the conventional methods, makes this protocol practical, environmentally friendly and economically desirable. The cellulose-SO3H (CSA) was characterized by FT-IR spectroscopy, powder X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM) analyses, and catalyst stability was judged by thermogravimetry/differential thermal analysis (TG/DTA). The catalyst can be recycled several times without significant loss of catalytic activity.
