We investigate the cross‐section asset‐pricing patterns of major cryptocurrencies from 2017 to 2021. We show that the basis, momentum, and basis–momentum factors earn statistically significant excess returns, a result consistent with the findings reported in the commodity futures literature. The basis is the strongest signal predicting cross‐sectional differences in cryptocurrency futures returns; the momentum‐induced risk premium is not statistically powerful, whereas the basis momentum‐induced risk premium disappears when accounting for the basis‐induced risk premium. Daily factor returns are statistically much stronger than weekly factor returns. Monthly factor returns are nonsignificant. [ABSTRACT FROM AUTHOR]

We investigate the effectiveness of various volatility models using China's Shanghai Stock Exchange‐50 (SSE50) Index. Regarding in‐sample fit, the generalized autoregressive conditional heteroscedasticity (GARCH) and the variants of the GARCH model perform much better than the autoregressive conditional heteroscedasticity model. However, we do not observe any significant asymmetric volatility response to past returns in the GJR–GARCH model. For out‐of‐sample forecasting of the future realized volatility, in five of the seven options we investigate, the GARCH volatility forecast outperforms the option implied volatility. We formulate a trading strategy by exploiting the spread between the GARCH volatility forecast and the option implied volatility, and show robust profits when applied to the SSE50 options.

An in situ generated oxidation species of nickel quinolinylpropioamide intermediate was produced. Characterization by X‐ray absorption near edge structure (XANES) and EPR provides complementary insights into this oxidized nickel species. With aliphatic amides and isocyanides as substrates, a nickel‐catalyzed facile synthesis of structurally diverse five‐membered lactams could be achieved.

An unanticipated and highly efficient selective amidation in the C2 position of 8‐amidoquinolines has been developed via C‐H bond elaboration. The method is transition‐metal‐free, operationally simple with broad functional group tolerance. In this work, isocyanide has been successfully utilized as the source of amide. Furthermore, various kinds of 8‐amidoquinolines in combination with different substituted isocyanides under oxidative condition resulted in direct access to N‐quinoline‐2‐carboxamides in good yields.

Transition metal-catalyzed isocyanide insertion has served as a fundamental and important chemical transformation. Classical isocyanide insertion usually occurs between organohalides and nucleophiles, which normally involves tedious and non-atom-economical prefunctionalization processes. However, oxidative C−H/N−H isocyanide insertion offers an efficient and green alternative. Herein, a nickel-catayzed oxidative C−H/N−H isocyanide insertion of aminoquinoline benzamides has been developed. Different kinds of iminoisoindolinone derivatives could be synthesized in good yields by utilizing Ni(acac)2 as the catalyst. In this transformation, isocyanide serves as an efficient C1 connector, which further inserted into two simple nucleophiles (C−H/N−H), representing an effective way to construct heterocycles.

The highly efficient copper(I)-catalyzed cascade reaction of ( E)-3-(2-isothiocyanatophenyl)acrylates and ( E)-3-(2-isothiocyanatophenyl)acrylonitriles with isocyanides was explored. The method provides an expedient route for the synthesis of 5 H-benzo[ d]imidazo[5,1- b][1,3]thiazines in good to excellent yields by using CuCl (10 mol-%) as the catalyst and K3PO4 (2.0 equiv.) as the base in THF at 70 °C. The reaction involves [3+2] cycloaddition and subsequent intramolecular C-S bond formation. [ABSTRACT FROM AUTHOR]
