Two efficient one-pot sequential coupling routes to 2-amino-3-arylbenzofurans and 2-amino-3-arylnaphtho[2,1-b]furans I (R = Cl, propan-2-yl, Ph, etc.; R1 = H, OMe, Ph; RR1 = -OCH2O-; R2 = H, Me; R3 = H, OMe; RR3 = -CH=CH-CH=CH-; Ar = 4-hydroxy-3-methoxyphenyl, thiophen-2-yl, 6-bromo-2H-1,3-benzodioxol-5-yl, etc.) were established. Further ring formation (six- and seven-membered rings) with the resulting amine moiety at the C2 position of benzofurans I were realized, leading to further expansion of benzofuran-based chem. space.

Ojha, Subhadra published the artcileN-Methoxy arenesulfonamide as a Sulfonyl Equivalent For Palladium-Catalyzed Sulfonylation of Arenes Through C-H Activation, Formula: C8H10O2, the main research area is diaryl sulfone preparation; arene methoxy arenesulfonamide sulfonylation carbon hydrogen activation palladium catalyst.

A palladium-catalyzed protocol for synthesizing diaryl sulfones RS(O)2R1 (R = Ph, 1-naphthyl, 2-thienyl, etc.; R1 = Ph, 2,4,6-trimethylphenyl, 2-naphthyl, etc.) from the arenes R1H through C-H activation is described. N-methoxy arenesulfonamide RS(O)2NHOMe was exploited as a potential sulfonyl donor by the cleavage of S-N bond through a radical pathway. The present methodol. has several advantages: a simple, readily available catalytic system; the use of a stable sulfonyl donor; a relatively moderate excess of arene coupling partner for an undirected C-H activation process, along with the tolerances of aryl bromides and iodides, which in turn permits further cross-coupling reactions to afford cross-coupled sulfones.

Rh-catalyzed reactions of N-alkyl anilines with internal alkynes at room temperature have been developed using an in situ generated N-nitroso group as a transient oxidizing directing group. Due to mild reaction conditions, this method enabled synthesis of a broad range of N-alkyl indoles, including even two indole-based medicinal compds I (R1 = Me, allyl, C6H5, etc.; R2 = 5-Me, 6-CH2OMe, 5-NO2, etc.) and II (R1 = Me, Et, i-Pr, etc.; R2 = H, 5-Me, 5-CO2Me, etc.; R3 = n-Bu, C6H5, 4-MeC6H5, etc.; R4 = Me, COMe, 3-FC6H5, etc.). This work disclosed the feasibility of the transient oxidizing directing group strategy in C-H functionalization reactions, which possesses the potential to enhance overall step-economy and impart new reactivity patterns to substrates.

Lui, Yuen Wai published the artcileMethylation with Dimethyl Carbonate/Dimethyl Sulfide Mixtures: An Integrated Process without Addition of Acid/Base and Formation of Residual Salts, HPLC of Formula: 151-10-0, the main research area is methylphenol preparation; methylbenzoate preparation; phenylpropanenitrile preparation; alkylation; dimethyl carbonate; green solvent; lignin; organocatalysis.

Di-Me sulfide, a major byproduct of the Kraft pulping process, was used as an inexpensive and sustainable catalyst/co-reagent (Me donor) for various methylations with di-Me carbonate (as both reagent and solvent), which afforded excellent yields of O-methylated phenols and benzoic acids, and mono-C-methylated arylacetonitriles. Furthermore, these products could be isolated using a remarkably straightforward workup and purification procedure, realized by di-Me sulfide’s neutral and distillable nature and the absence of residual salts. The likely mechanisms of these methylations were elucidated using exptl. and theor. methods, which revealed that the key step involves the generation of a highly reactive trimethylsulfonium methylcarbonate intermediate. The phenol methylation process represents a rare example of a Williamson-type reaction that occurs without the addition of a Bronsted base.

Bomon, Jeroen published the artcileEfficient demethylation of aromatic methyl ethers with HCl in water, Recommanded Product: 1,3-Dimethoxybenzene, the main research area is alc aryl preparation green chem; aryl methyl ether demethylation hydrochloric acid catalyst.

A green, efficient and cheap demethylation reaction of aromatic Me ethers, e.g., 2H-1,3-benzodioxole-5-carbaldehyde with mineral acid (HCl or H2SO4) as a catalyst in high temperature pressurized water provided the corresponding aromatic alcs.e.g., 3,4-dihydroxybenzaldehyde in high yield. 4-Propylguaiacol was chosen as a model, given the various applications of the 4-propylcatechol reaction product. This demethylation reaction could be easily scaled and biorenewable 4-propylguaiacol from wood and clove oil could also be applied as a feedstock. Greenness of the developed method vs. state-of-the-art demethylation reactions was assessed by performing a quant. and qual. Green Metrics anal. Versatility of the method was shown on a variety of aromatic Me ethers containing (biorenewable) substrates, yielding up to 99% of the corresponding aromatic alcs., in most cases just requiring simple extraction as work-up.
