A cascade radical cyclization of 2-isocyanoaryl thioethers with H-phosphorus oxides, organoboronic acids, or alkyl radical precursors has been efficiently developed, providing a novel and highly efficient methodology to structurally diverse C2-substituted benzothiazole derivatives with broad functional group tolerance and good yields. This cascade radical process achieves the first cycloaddition of an imidoyl radical from isocyanide to sulfur atom, rending C(sp2)-S bond formation.

In a Review，once mentioned of 17261-28-8, Safety of 2-(Diphenylphosphino)benzoic acid

Nitroxyl (HNO), which according to the IUPAC recommended nomenclature should be named azanone, is the protonated one-electron reduction product of nitric oxide. Recently, it has gained a considerable attention due to the interesting pharmacological effects of its donors. Although there has been great progress in the understanding of HNO chemistry and chemical biology, it still remains the most elusive reactive nitrogen species, and its selective detection is a real challenge. The development of reliable methodologies for the direct detection of azanone is essential for the understanding of important signaling properties of this reactive intermediate and its pharmacological potential. Over the last decade, there has been considerable progress in the development of low-molecular-weight fluorogenic probes for the detection of HNO, and therefore, in this review, we have focused on the challenges and limitations of and perspectives on nitroxyl detection based on the use of such probes.

While MoIr3(mu-CO)3(CO)7(eta5-C5H5) reacted with HC?CSiMe3 to give a complex mixture of thus-far-uncharacterized products, its phosphine substitution product MoIr3(mu-CO)3(CO)5(PPh3)2(eta5-C5H5) reacted with the same alkyne via insertion into a Mo-Ir bond to afford the pseudo-octahedral MoIr3(mu4-eta2-HC2SiMe3)(mu-CO)3(CO)4(PPh3)2(eta5-C5H5) (8) in good yield. Clusters 4, 5 (two isomers), 6 and 8 have been characterized by single-crystal X-ray diffraction studies. Cyclic voltammetric studies of Mo2Ir2(mu-CO)3(CO)6(PPh3)(eta5-C5H5)2 (2), 3-6 and 8 confirmed the tuning of redox potentials upon phosphines/arsine introduction and alkyne modification. IR spectroelectrochemical studies of 2, 6, and 8 suggest decreasing proclivity for bridging carbonyl ligands following oxidation. Variable temperature 31P NMR studies of 3 and 4 revealed interconverting isomers in solution, the structures of which are assigned as analogues of the X-ray diffraction-confirmed isomers of 5. Studies of 2-5 using ns pulses and the open-aperture Z-scan technique revealed that all are optical limiters at wavelengths in the visible region.

You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.1038-95-5, Name is Tri-p-tolylphosphine, molecular formula is C21H21P. In a patent, introducing its new discovery.

Silver nitrate reacts with salicylic acid (salH2) or p-hydroxy-benzoic acid (p-HbzaH2) and equimolar amount of NaOH to yield a white precipitations which are then treated with tri(p-tolyl)phosphine (tptp) or tri(m-tolyl)phosphine (tmtp) to yield the complexes [Ag(tptp)2(salH)] (1), [Ag(tptp)2(p-Hbza)] (2) and [Ag(tmtp)2(salH)] (3). Complexes 1 and 3 are also obtained when aspirin (aspH) is used. The acetic ester of salicylic acid is hydrolyzed to form the complexes 1 and 3. However, when aspirin and tptp are used, a mixture of products was obtained which contains both 1 and an ionic complex of formula {[Ag(tptp)4]+[(salH)-][(CH3)2NCHO)](H2O)} (1a). The complexes were characterized by m.p., e.a., mid-FT-IR, 1H-,31P-NMR, HRMS, UV-vis spectroscopic techniques and X-ray crystallography. Two phosphorus and one carboxylic oxygen atoms form a trigonal planar geometry around Ag(I) ions in complexes 1-3. Complex 1a consists of a [Ag(tptp)4]+ cation and a deprotonated salH- counter anion. The influence of 1-3 on the viability of MCF-7 (breast) and HeLa (cervix) adenocarcinoma cells, is evaluated. DNA binding tests indicate the ability of 1-3 to modify the activity of cells. The binding constants of 1-3 towards calf-thymus DNA, reveal stronger interaction of 2. Changes in fluorescent emission light of ethidium bromide (EB) in the presence of DNA suggest intercalation or electrostatic interactions into DNA for 1 and 3. Docking studies on DNA-complex interactions confirm the binding of 1-3 in the minor groove of B-DNA. Moreover, the influence of 1-3 on the peroxidation of linoleic acid to hydroperoxylinoleic acid by the enzyme lipoxygenase (LOX) was kinetically and theoretically studied.

The development of n-type polymers and composites to pair with their p-type counterparts in current flexible thermoelectric (TE) generators is crucial to reach the full potential of these devices. However, this development has lagged behind because of difficulties associated with n-type doping of organic semiconductors. Our study focused on the doping characteristics of directly spun carbon nanotube (CNT) webs using various n-type dopants in combination with thermal desorption of oxygen from the CNT web surface for more effective n-type doping. Annealing of the CNT web followed by treatment with 2 mg mL-1 benzyl viologen (BV) resulted in a maximum power factor of 3103 muW m-1 K-2, which was superior to that of a BV-treated pristine CNT web without thermal annealing (1901 muW m-1 K-2). This value is the highest among organic TE materials and similar to that of the most promising inorganic material, Bi2Te3 at room temperature. In addition to the effect of BV dopants on the electrical properties, the thermal diffusion property of the BV-doped CNT web was analyzed using the finite element method. The dopant coating on the CNT bundle efficiently suppressed the phonon transfer along the CNT web direction, which led to a reduction of the thermal conductivity of the CNT web. As a counterpart for the n-type CNT web, p-type TE materials with a thermal power of 2252 muW m-1 K-2 were also prepared using molecular dopants of 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane. Finally, a p-n junction-type TE module with an unprecedented power density of 1.18 mW cm-2 was fabricated based on the development of these competitive n-type TE materials.
