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.

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).

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.

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].

Convenient iron-catalyzed reductive aminations without hydrogen for selective synthesis of N-methylamines

N-Methylated amines play an important role in regulating the biological and pharmaceutical properties of all kinds of life science molecules. In general, this class of compounds is synthesized via reductive amination reactions using high pressure of molecular hydrogen. Thus, on laboratory scale especially in drug discovery, activated (toxic) methyl compounds such as methyl iodide and dimethyl sulfate are still employed, which also generate significant amounts of waste. Therefore, the development of more convenient and operationally simple processes for the synthesis of advanced N-methylamines is highly desired. Herein, we report the synthesis of functionalized and structurally diverse N-methylamines directly from nitroarenes and paraformaldehyde, in which the latter acts as both methylation and reducing agent in the presence of reusable iron oxide catalyst. The general applicability of this protocol is demonstrated by the synthesis of >50 important N-methylamines including highly selective reductive N-methylations of life science molecules and actual drugs, namely hordenine, venlafaxine, imipramine and amitriptyline.

Mono- versus dipalladation of the durene-based tetrathioether ligand 1,2,4,5-(tBuSCH2)4C6H2. Structures of [PdCl((tBuSCH2)4C6H)] and [Pd2((tBuSCH2)4C6)(MeCN) 2][BF4]2

Treatment of 1,2,4,5-(tBuSCH2)4C6H2 with K2PdCl4/NaOAc in ethanol yielded only the monopalladated complex [PdCl((tBuSCH2)4C6H)] regardless of whether 1 or 2 equiv of K2-PdCl4 is used. Alternately, the reaction of 1,2,4,5-(tBuSCH2)4C6H2 with 1 or 2 equiv of [Pd-(MeCN)4][BF4]2 in MeCN resulted in quantitative production of the dipalladated species [Pd2((tBuSCH2)4C6)(MeCN) 2][BF4]2 based on palladium starting material. The X-ray structures of the two products [PdCl((tBuSCH2)4C6H)] and [Pd2((tBuSCH2)4C6)(MeCN) 2][BF4]2 are reported. MO calculations were consistent with the idea that the ligand trans to the first Pd-C bond dictates the electrophilic aromatic substitution pattern and determines whether a second palladation will occur. Thus, Pd-Cl is deactivating while (Pd-MeCN)+ is activating, resulting in the formation of exclusively mono- and dipalladated products, respectively.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C8H12B2F8N4Pd, you can also check out more blogs about21797-13-7
