Structurally Simple and Easily Accessible Perylenes for Dye-Sensitized Solar Cells Applicable to Both 1 Sun and Dim-Light Environments

The need for low-cost and highly efficient dyes for dye-sensitized solar cells under both the sunlight and dim light environments is growing. We have devised GJ-series push-pull organic dyes which require only four synthesis steps. These dyes feature a linear molecular structure of donor-perylene-ethynylene-arylcarboxylic acid, where donor represents N,N-diarylamino group and arylcarboxylic groups represent benzoic, thienocarboxylic, 2-cyano-3-phenylacrylic, 2-cyano-3-thienoacrylic, and 4-benzo[c][1,2,5]thiadiazol-4-yl-benzoic groups. In this study, we demonstrated that a dye without tedious and time-consuming synthesis efforts can perform efficiently. Under the illumination of AM1.5G simulated sunlight, the benzothiadiazole-benzoic-containing GJ-BP dye shows the best power conversion efficiency (PCE) of 6.16% with VOC of 0.70 V and JSC of 11.88 mA cm-2 using liquid iodide-based electrolyte. It also shows high performance in converting light of 6000 lx light intensity, that is, incident power of ca. 1.75 mW cm-2, to power output of 0.28 mW cm-2 which equals a PCE of 15.79%. Interestingly, the benzoic-containing dye GJ-P with a simple molecular structure has comparable performance in generating power output of 0.26 mW cm-2 (PCE of 15.01%) under the same condition and is potentially viable toward future application.

Palladium-Catalyzed Intramolecular Self-Alkylation of Polyfluoroarene via Heck and Decarboxylation Process

An efficient palladium-catalyzed cyclization and polyfluorophenylation of gamma,delta-unsaturated polyfluorobenzoyl oxime ester via iminopalladation/polyfluorobenzoyloxy decarboxylation cascade reaction is developed. The protocol provides a practical and atom-economical access to a broad scope of various polyfluorophenylated dihydropyrrole derivatives. The reaction effectively utilizes the polyfluorobenzoyloxy leaving group as polyfluorophenylated source for the first time, precluding the need of additional polyfluoroarene. This is the first example of the introduction of electron-deficient arenes in the further transformation of Narasaka-Heck-type reaction. Additionally, the reaction is conducted in a short time.

Palladium-catalyzed cross-coupling of benzyl chlorides with cyclopropanol-derived ketone homoenolates

The palladium-catalyzed cross-coupling reaction of cyclopropanol-derived ketone homoenolates with benzyl chlorides is reported. This reaction proceeds in high yields with electron-neutral and electron-rich benzyl chlorides; however, yields are low with electron-poor benzyl chlorides. In addition, a range of cyclopropanols can be coupled in good yields. The reaction can be conducted with a low catalyst loading (1% Pd) and on a gram scale without reduction in yield.

Mechanistic study of the Pd/TOMPP-catalyzed telomerization of 1,3-butadiene: Influence of aromatic solvents on bis-phosphine complex formation and regioselectivity

A study of the influence of reaction conditions on the Pd/TOMPP-catalyzed (TOMPP = tris(2-methoxyphenyl)phosphine) telomerization of 1,3-butadiene with phenols revealed that the composition of the reaction medium strongly influences the regioselectivity of the telomer products. Mechanistic studies show this effect to be related to the stability of the key catalytic intermediate cis-[Pd((1-3eta)-octa-2,7-dien-1-yl)(TOMPP)2]+ (E), which mainly depends on the solvent composition. The crotyl analogue cis-[Pd((1-3eta)-but-2-en-1-yl)(TOMPP)2]BF4 (4) was synthesized as a model for E and was fully characterized, including by an X-ray crystal structure determination. Comparison of the crystal structures of 4 and [Pd((1-3,7,8eta)-octa-2(E),7-dien-1-yl)(TOMPP)]BF4 (1), an analogue of intermediate C, shows that the difference in regioselectivity for nucleophilic attack of these complexes is not reflected in the structure of the allyl moiety. Furthermore, Pd/TOMPP-catalyzed n/iso equilibration reactions of telomers show that all product formation routes in the Pd-catalyzed telomerization mechanism are reversible. Telomer product equilibration studies resulted in complete conversion to 1,3,7-octatriene, with the selectivity changing over time in favor of formation of the Z isomer of octatriene.

Convenient synthesis of 1H-indol-1-yl boronates via palladium(0)-catalyzed borylation of bromo-1H-indoles with ‘pinacolborane’

An atom-economic Pd0-catalyzed synthesis of a series of pinacol-type indolylboronates 3 from the corresponding bromoindole substrates 2 and pinacolborane (pinBH) as borylating agent was elaborated. The optimal catalyst system consisted of a 1:2 mixture of [Pd(OAc)2] and the ortho-substituted biphenylphosphine ligand L-3 (Scheme 4, Table).
