Synthesis of neoflavenes by a palladium-catalyzed cross-coupling reaction of 4-trifluoromethylsulfonyloxy-2H-chromenes with arylboronic acids

Under anhydrous conditions, 4-phenyl-2H-chromenes were obtained in excellent yields by a cross-coupling reaction of 4-trifluoromethylsulfonyloxy-2H-chromenes with arylboronic acids, except for o-methoxyphenylboronic acid, in the presence of K2CO3 and several palladium catalysts. Although copper(I) iodide, used as a co-catalyst, showed no effect on this reaction, it was confirmed to act in the case of the coupling reaction of 4-trifluoromethylsulfonyloxy-2H-chromene with tributylphenyltin, instead of phenylboronic acid, in the presence of [Pd(PPh3)4].

Synthesis of a class of binaphthyl monophosphine ligands with a naphthofuran skeleton and their applications in Suzuki-Miyaura coupling reactions

A series of new monophosphine ligands containing a naphthofuran skeleton have been prepared, characterized and evaluated in palladium-catalyzed Suzuki-Miyaura coupling reactions. Using Pd2(dba)3-L6 as the catalyst the reactions were performed with high catalytic activity under mild reaction conditions and the desired coupling products were obtained in good to excellent yields. The new catalyst system also showed broad substrate adaptability and practicality for gram-scale production.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Regular terpolymers with fluorinated bithiophene units for high-performing photovoltaic cells

We demonstrate effective structural control of various electron-donating moieties containing bithiophene (BT) and naphthalene derivatives with 3,3?-difluoro-2,2?-bithiophene in a regular terpolymer system and compare the properties of these polymers with those of the three binary copolymers PDPPNp, PDPPBT, and PDPPFBT. PDPPBF and PDPPNF were successfully synthesized to be diketopyrrolopyrrole (DPP)-based terpolymers. The optical and electronic properties of these regular terpolymers could be precisely controlled by introducing three different components in the repeating units. A polymer solar cell (PSC) made of PDPPNF, which contains naphthalene as a weak donating unit, had a high open-circuit voltage (Voc) of 0.77 V, resulting from a relatively deep HOMO energy level. In contrast, PDPPBF bearing BT, which is an example of a relatively strong electron-donating unit, had a higher short-circuit current density (Jsc = 13.44 mA cm-2) than that of PDPPFBT. Therefore, improved power conversion efficiency (PCE) was possible in a PSC made of PDPPBF containing the electron-donating bithiophene unit in the terpolymer backbone. However, the improved internal morphology, as characterized by AFM and TEM, was the primary contributor to the enhanced PCEs (i.e., 6.38% and 6.39% for PDPPBF and PDPPNF, respectively).

Palladium-Catalyzed Synthesis of 5-Iminopyrrolones through Isocyanide Double Insertion Reaction with Terminal Alkynes and Water

With the combination of Pd(dppf)Cl2 and Cu(OAc)2, a variety of 5-iminopyrrolones were synthesized in moderate to good yields from terminal alkynes, isocyanide, and water via isocyanide double insertion and cycloaddition reaction. A plausible reaction mechanism for this process is depicted. Furthermore, selected compounds 3c, 3e, and 3h exhibited good activities against HepG2 (human liver cancer), NCI-H460 (human lung cancer), and SK-OV-3 (human ovarian cancer) cell lines with IC50 values in the range of 10.63-22.63 mumol L-1.

Spin Crossover in New Iron(II) Complexes with 2,6-Bis(benzimidazole-2-yl)pyridine

Abstract: New coordination compounds of iron(II) sulfate, hexafluorosilicate, and perrhenate with 2,6-bis(benzimidazole-2-yl)pyridine (L), namely, [FeL2]SO4 ? H2O (I), [FeL2]SiF6 ? H2O (II), and [FeL2](ReO4)2 ? 1.5H2O (III) have been synthesized. The complexes have been studied by static magnetic susceptibility, electronic (diffuse reflectance), IR, and Moessbauer spectroscopy, and X-ray diffraction. The mueff(T) study of dehydrated complexes I?III (1?3) within the range 80?520 K has shown the spin transition 1?1 ? 5?2. A two-stage transition is observed in complex 1, whereas one-stage transitions occur in complexes 2 and 3. The forward spin transition temperatures (???) of complexes 1?3 are 423 and 503, 476, 362 K, respectively. Complex 3 sustains an abrupt spin transition with a hysteresis in the mueff(T) curve (DeltaT = 21 K).
