5Recent advances in the synthesis of 1,1-diarylalkanes by transitionmetal catalysis显示文摘1,1-Diaryl moieties are core structures in a wide range of bioactive and pharmaceutical compounds.Transition-metal catalysis is a convenient approach to accessing these invaluable compounds affording high yields and enantioselectivities.This review summarizes 1,1-diarylalkanes synthesis through transition metal catalysis.Particular focus is given to recent developments,such as reductive cross-electrophile couplings,benzylic C–H bond arylation,transformations involving metal migration,asymmetric hydrogenation of 1,1-diarylalkenes and three-component coupling reactions.Md.Belal Zheqi Li Xiuqiang Lu Guoyin Yin 2021Science China Chemistry2021,64,4:1

7Modular Synthesis of Diarylalkanes by Nickel-Catalyzed 1,1-Diarylation of Unactivated Terminal Alkenes显示文摘A nickel-catalyzed 1,1-diarylation of electronically unbiased alkenes has been developed,providing straightforward access to diarylalkanes from readily available materials.Importantly,both the efficiency and the regioselectivity of this transformation are ensured by reaction conditions,rather than the coordinating group of substrates.We also demonstrate that under balloon pressure,ethylene and propylene can also be utilized as substrates.Preliminary mechanistic experiments suggest that this transformation involves a Ni(0)/Ni(Ⅱ)catalytic cycle rather than a Ni(Ⅰ)/Ni(Ⅲ)cycle.Zheqi Li Dong Wu Chao Ding Guoyin Yin 2021CCS Chemistry2021,3,1:1

9A Review of Nonlinear Kalman Filter Appling to Sensorless Control for AC Motor Drives显示文摘Sensorless control of AC motor drives,which takes the advantages of cost saving,higher reliability,and less hardware,has been developed for several decades.Among the existing speed sensorless control methods,nonlinear Kalman filter-based one has attached widespread attention due to its superb estimation accuracy and inherent resistibility to noise.However,the determination of noise covariance matrix and robustness of model uncertainties are still open issues in practice.A great number of studies try to solve these problems in resent years.This paper reviews the application of extended Kalman filter(EKF),unscented Kalman filter(UKF),and cubature Kalman filter(CKF)in speed sensorless control for AC motor drives.As an iterative algorithm,EKF has advantages in processor implementation.However,EKF suffers from the linearization error and model uncertainties when applying to sensorless control system.This paper presents the predominant improvements of EKF which is also applicative in UKF and CKF mostly.Zhonggang Yin Fengtao Gao Yanqing Zhang Chao Du Guoyin Li Xiangdong Sun 2019CES Transactions on Electrical Machines and Systems2019,3,4:0
101,1-Regioselective alkenylboration of styrenes enabled by palladium catalysis显示文摘Despite the 1,2-difunctionalization reactions of styrenes have been well developed, the 1,1-regioselective addition reaction remains challenging. We disclose herein a palladium-catalyzed, highly 1,1-regioselective alkenylboration of styrenes by using alkenyl triflates and a diboron reagent as the coupling partners. A wide scope of styrenes derivatives and alkenyl triflates participate this reaction to provide the corresponding allyl boronates with high regioisomeric ratios. The success of this reaction is ascribed to the application of 1,10-phenanthroline-derivated ligand and the addition of ammonium chloride salt. Moreover, acrylate esters can also selectively afford the 1,1-alkenylboration products under the same reaction conditions.Dong Wu Hailiang Pang Guoyin Yin 2023Chinese Chemical Letters2023,34,8:0
11Integrating aryl chlorides into nickel-catalyzed 1,1-difunctionalization of alkenes显示文摘Difunctionalization of alkenes have developed into an important type of reactions for rapidly and efficiently assemble complex molecules.While extensive advancements have been achieved by the assistance of transition metal catalysis,the employment of cheap,abundant aryl chlorides as coupling partner is still a challenging task in this field.Herein,we report our first achievement in 1,1-difunctionalization of alkenes with aryl chlorides as coupling partners.The success is predominantly ascribed to the judicious selection of 1,2-diamine ligand.This study provides an efficient protocol for the synthesis of secondary benzyl boronates from easily accessible feedstock chemicals.Furthermore,the distinguished features of this method include excellent 1,1-regio-and chemoselectivity,good functional group tolerance and easily-operational catalytic reaction conditions.Caocao Sun Guoyin Yin 2022Chinese Chemical Letters2022,33,12:0
12Catalyst-controlled regiodivergent 1,2-difunctionalization of alkenes with two carbon-based electrophiles显示文摘Regiodivergent catalysis provides an efficient strategic approach for the construction of architecturally different molecules from the same starting materials. In this field, the intermolecular regiodivergent 1,2-difunctionalization of alkenes with two electrophiles is still a challenging task. A ligand-controlled, nickel-catalyzed regiodivergent dicarbofunctionalization of alkenes using both aryl/vinyl halides and acetals as electrophiles under mild reductive reaction conditions has been accomplished. This study provides a general approach to accessing both β-methoxyl esters and γ-methoxyl esters from readily available acrylates,aryl halides and acetals. Experimental mechanistic evidence supports that the difference in regioselective outcomes is attributed to the ligand tuning the reactivity of the nickel catalyst, which results in different catalytic cycles operating for these two reaction conditions.Md.Belal Zheqi Li Lei Zhu Guoyin Yin 2022Science China Chemistry2022,65,3:0
