Dehydrogenative (Hetero)arene Alkoxylations Triggered by PdII‐Catalyzed C(sp2)–H Activation and Coordinating Substituent: PdII,III or PdIV Complex as Key Intermediate?

“…(32) The Pd(OAc) 2 /PhI(OAc) 2 system was subsequently used for the alkoxylation of N-[2-(pyridin-2-yl)propan-2-yl]benzamides (33) (34) and 2-aryl-N-[2-(pyridin-2-yl)propan-2-yl]acetamides at 90°C in 1:1 mixtures of p-xylene and a primary or secondary alcohol. [48] Dialkoxylated products were obtained in moderate to high yields [Equation (35)] except in the cases of substrates bearing a meta substituent, which were monomethoxylated [Equation (36)]. Similar reaction conditions were recently used for the efficient monomethoxylation of N-(benzo[c][1,2,5]thiadiazol-4yl)benzamides [Equation (37)].…”

“…It also seems of interest to mention the para-methoxylation of N-(quinolin-8-yl)butyramide, which cannot involve C(sp 2 )-H activation through a palladium chelate [Equation (62)]. [48,64,65] Scheme 5. Reluctant substrates.…”

Dual‐Mode Calixarene‐Based Chemosensor: Highly Selective Fluorogenic Detection of Hg2+ and Chromogenic Detection of Cu2+ with a Single Ionophore

“…[4,59,63] The enhancement in emission intensity upon addition of Hg 2+ is due to the interaction of the metal ion with the nitrogen donors in the calix-aza-crown moiety, which restricted the intramolecular reductive electron transfer (PeT) quenching process, as the nitrogen atoms of the azacrown moiety binds with the positively charged metal ion. [30,47,57,59,64,65] The ESI-MS of 1 upon addition of Hg 2+ (5 fold excess) in acetonitrile exhibited 1:1 complex formation, the observed m/z peaks at 1258.75 and 1299.86 correspond to [1 -2H + -Cl -+ Hg 2+ ] + (calcd. 1258.34) and [1 -2H + -Cl -+ Hg 2+ + CH 3 CN] + (calcd.…”

“…Binding of Hg 2+ with soft donor atoms such as nitrogen leaving oxygen uncoordinated has been demonstrated with similar calixarene-based ionophore. [27,64,69] On the other hand, preferential binding of Cu 2+ with harder donor atoms, which includes oxygen atoms of the OH, C=O and ether moiety has also been demonstrated. [37] Therefore, the two metal ions are not in competition for the same site, once one metal ion is coordinated, it has blocked the entry of another metal ion.…”

Exploring MicroRNA Expression Profiles Related to the mTOR Signaling Pathway in Mouse Embryonic Fibroblast Cells Treated with Polyethylenimine

“…29,30 Among these three up-regulated miRNAs, miR-494-3p has been reported to suppress the progression and metastasis of prostate cancer. 31 Overexpressed miR-494-3p has been shown to inhibit the growth and paracrine function of mesenchymal stem cells by targeting of Cdk6, Ccnd1 and VEGF. 32 Furthermore, a mouse model has revealed that miR-494-3p is related to glioma proliferation and invasion.…”
