Insects that can perform flapping-wing flight,climb on a wall,and switch smoothly between the 2 locomotion regimes provide us with excellent biomimetic models.However,very few biomimetic robots can perform complex locomotion tasks that combine the 2 abilities of climbing and flying.Here,we describe an aerial–wall amphibious robot that is self-contained for flying and climbing,and that can seamlessly move between the air and wall.It adopts a flapping/rotor hybrid power layout,which realizes not only efficient and controllable flight in the air but also attachment to,and climbing on,the vertical wall through a synergistic combination of the aerodynamic negative pressure adsorption of the rotor power and a climbing mechanism with bionic adhesion performance.On the basis of the attachment mechanism of insect foot pads,the prepared biomimetic adhesive materials of the robot can be applied to various types of wall surfaces to achieve stable climbing.The longitudinal axis layout design of the rotor dynamics and control strategy realize a unique cross-domain movement during the flying–climbing transition,which has important implications in understanding the takeoff and landing of insects.Moreover,it enables the robot to cross the air–wall boundary in 0.4 s(landing),and cross the wall–air boundary in 0.7 s(taking off).The aerial–wall amphibious robot expands the working space of traditional flying and climbing robots,which can pave the way for future robots that can perform autonomous visual monitoring,human search and rescue,and tracking tasks in complex air–wall environments.

Synthesis of amidines via iron-catalyzed dearomative amination of β-naphthols with oxadiazolones

引用

Organic Chemistry Frontiers 2022年第2期9卷 380-385页

作者： Yan-Hui Fan Xiao-Yu Guan Wen-Pei Li Cheng-Zhou Lin De-Xian Bing Mei-Zhi Sun Guo Cheng Jing Cao Jun-Jie Chen Qing-Hai Deng The Education Ministry Key Lab of Resource Chemistry Joint International Research Laboratory of Resource ChemistryMinistry of EducationShanghai Key Laboratory of Rare Earth Functional Materialsand Shanghai Frontiers Science Center of Biomimetic CatalysisCollege of Chemistry and Materials ScienceShanghai Normal UniversityShanghai 200234China

An iron-catalyzed dearomative amination of β-naphthols via a nitrene-transfer process has been developed.Oxadiazolones,which have rarely been applied for the synthesis of amidines,are used as the nitrene source.A variety of amidines bearing β-naphthalenone moieties were generated smoothly in good to high yields(up to 98%)in the presence of 1.5 equivalents of tetrabutylammonium bromide,which was added as an essential additive.

Platinum–P(BFPy) 3 -catalyzed regioselective diboration of terminal alkynes with (pin)B–B (aam)

引用

Organic Chemistry Frontiers 2022年第5期9卷 1370-1374页

作者： Ikuo Kageyuki Jialun Li Hiroto Yoshida Graduate School of Advanced Science and Engineering Hiroshima UniversityHigashi-Hiroshima 739-8526Japan

An unsymmetrical diboron,(pin)B–B(aam),is smoothly added across a carbon–carbon triple bond of various terminal alkynes under platinum catalysis,resulting in the regio-and stereoselective formation of cis-vic-diborylalkenes via B(aam)-installation at the terminal carbon.The use of a highly electron-deficient triarylphosphine ligand,P(BFPy)_(3),is indispensable for the regiocontrol,and electron-deficiency in ligands has been proven to be closely correlated with the regioselectivity.

Cu( II )-Catalyzed C2-site functionalization of p-aminophenols: an approach for selective cross-dehydrogenative aminations

引用

Organic Chemistry Frontiers 2022年第4期9卷 1010-1015页

作者： Xin Zhao Fang Yang Lin-Lin Wang Jing Guo Yu-Qin Xu Zi-Sheng Chen Kegong Ji College of Chemistry and Pharmacy Northwest A&F UniversityShaanxi Key Laboratory of Natural Products&Chemical Biology3 Taicheng RoadYangling712100 ShaanxiP.R.China School of Pharmacy Baotou Medical CollegeBaotou 014060Inner MongoliaP.R.China Guangdong Provincial Key Laboratory of Catalysis Southern University of Science and TechnologyShenzhen 518055China

Site selective cross dehydrogenative aminations from precursors without preactivated C–H and N–H bonds have been challenging.Herein,a copper-catalyzed C2-site selective amination of p-aminophenol derivatives with arylamines has been developed.This approach precludes both partners from prefunctio-nalization and yields single site selective aminated products.This reaction proceeds smoothly with air as a terminal oxidant to produce the corresponding C2-site functional aminophenol derivatives in moderate to good yields.

The generation of methylsufonyl-containing thioflavones through a radical relay reaction of methylthiolated phenylalkynones and potassium metabisulfite in the presence of a catalytic amount of sodium methylsulfinate as an initiator under photoinduced conditions is developed.This photocatalytic reaction proceeds smoothly with good functional group tolerance under visible light irradiation.Preliminary mechanistic investigations indicate that this reaction occurs through a radical relay pathway.
