The tertiary amine and ketone components of 1-carbonyl-substituted anilines underwent [1,2] and [2,3] Stevens rearrangement reactions, triggered by a C4F9 radical, formed from electron donor-acceptor complexes. This approach enabled the formation of a quaternary ammonium salt and thus a Stevens rearrangement to afford indolin-3-ones such as I [R1 = Me, Et, i-Pr; R2 = Bn, CH2CH=CH2, C(Me)=C=CH2, etc.; R3 = Me, Bn] and II [R4 = H, Cl, Br; R5 = H, MeO, Cl; R6 = H, MeO] under mild conditions.

Sathishkumar, Pushpanathan N. published the artcileTuning acylthiourea ligands in Ru(II) catalysts for altering the reactivity and chemoselectivity of transfer hydrogenation reactions, and synthesis of 3-isopropoxy-1H-indole through a new synthetic approach, Synthetic Route of 1885-29-6, the main research area is ruthenium cymene complex preparation crystal structure; carbonyl compound ruthenium cymene complex catalyst chemoselective transfer hydrogenation; alc preparation; nitroarene ruthenium cymene complex catalyst chemoselective transfer hydrogenation; arylamine preparation.

Ru(II)-p-cymene complexes containing picolyl based pseudo-acylthiourea ligands were synthesized and characterized. The crystallog. study confirmed the mol. structures of all the ligands and one complex. The catalytic activity of the complexes was tested mainly towards transfer hydrogenation of carbonyl compounds and nitroarenes. The influence of steric and electronic effects of the ligands on the chemoselectivity and reactivity were reported. The catalytic activity was enhanced and chemoselectivity was switched after tuning the ligands in the catalysts, compared to their corresponding unmodified Ru(II)-p-cymene complexes. The catalysis was extended to a broad range of substrates including some challenging systems like furfural, benzoylpyridine, benzoquinone, chromanone, etc. The strategy of tuning the bifunctional ligands in the catalysts for effective and selective catalysis worked nicely. Further, the catalysis was extended to one-pot synthesis of 3-isopropoxyindole from 2-nitrocinnamaldehyde, the first synthetic route similar to Baeyer Emmerling indole synthesis. All the catalytic experiments exhibited high conversion and selectivity.

Mahmoudi, Boshra published the artcileOxidation/ MCR domino protocol for direct transformation of methyl benzene, alcohol, and nitro compounds to the corresponding tetrazole using a three-functional redox catalytic system bearing TEMPO/Co(III)-porphyrin/ Ni(II) complex, Product Details of C6H4N2, the main research area is alc methylbenzene nitro compound conversion tetrazole oxidation multicomponent domino; safety sodium azide.

A redox catalytic system for oxidation-reduction reactions and the domino preparation of tetrazole compounds from nitro and alc. precursors was designed, prepared and characterized by UV-vis, GPC, TGA, XRD, EDX, XPS, VSM, FE-SEM, TEM, DLS, BET, NMR, and ICP analyses [e.g., toluene → 5-phenyl-1H-tetrazole and nitrobenzene → 1-phenyl-1H-tetrazole]. The catalyst was prepared via several successive steps by demetalation of chlorophyll b, Schiff base formation with allylamine, copolymerization with acrylated TEMPO monomers, complexation with Ni and Co metals (in two different steps), then immobilized on magnetic nanoparticles. The presence of three functional groups including TEMPO, coordinated cobalt, and coordinated nickel in the catalyst, allowed the oxidation of various types of alcs., alkyl benzenes as well as the reduction of nitro compounds by a single catalyst. All reactions yielded up to 97% selectivity for oxidation and reduction reactions. Next, the ability of the catalyst to successfully convert benzylic alcs., methylbenzenes and nitro compounds to their corresponding tetrazoles was studied. Safety: extreme caution is required when handling sodium azide.

Lian, Zhong published the artcileCooperative redox activation for carbon dioxide conversion, Application In Synthesis of 42872-30-0, the main research area is diaryldisilane carbon dioxide aryl iodide palladium Hiyama Denmark coupling; diarylketone preparation.

The conversion of CO2 with diaryldisilanes, which through cooperative redox activation generated carbon monoxide and a diaryldisiloxane that actively participated in a palladium-catalyzed carbonylative Hiyama-Denmark coupling for the synthesis of an array of pharmaceutically relevant diarylketones was reported. Thus the disilane reagent not only served as the oxygen abstracting agent from CO2, but the silicon-containing ‘waste’, produced through oxygen insertion into the Si-Si bond, participated as a reagent for the transmetalation step in the carbonylative coupling. Hence this concept of cooperative redox activation opened up for new avenues in the conversion of CO2.

Bergagnini-Kolev, Mackenzie published the artcileSynthesis of trifluoromethyl substituted nucleophilic glycine equivalents and the investigation of their potential for the preparation of α-amino acids, Safety of 2-Aminobenzonitrile(Flakes or Chunks), the main research area is amino acid synthesis trifluoromethyl nucleophilic glycine equivalent; substituted pyroglutamic acid synthesis; nickel complex glycine Schiff base phase transfer catalyzed alkylation; oxazoladinone amide unsaturated substituted carboxylic acid Michael addition.

The synthetic preparation of several Ni(II) complexed Schiff bases of glycine will be introduced, as well as investigations into their reactivity and utility. Key to these investigations is the incorporation of electron-withdrawing trifluoromethyl groups within the framework of the conjugated system that stabilizes the enolate derived from the glycine component. Reactivity was evaluated for each of the complexes under phase transfer catalyzed alkylations with hydroxide bases, as well as the DBU catalyzed Michael additions of optically active 3′-substituted-2-oxazoladinone amides of unsaturated carboxylic acids. It was found that the trifluoromethyl containing nucleophilic glycine equivalent were more reactive than their non-trifluoromethyl analogs in both reaction types. Therefore, the application of these modified Ni(II) complexes of glycine Schiff bases are useful for the preparation of α-amino acids through phase transfer catalyzed alkylation as well as the preparation of optically pure β-substituted pyroglutamic acid precursors.
