We report an unprecedented C-H bond functionalization of cyclopropenes enabled by dinuclear gold catalysis.Highly selective C-H allylation,alkynylation and halogenation of cyclopropenes with organic halides have been realized.The reaction does not require strong external oxidants and affords access to functionalized cyclopropenes in moderate to good yields.The reductive elimination process to controllably construct C-C or C-X bonds can be tuned by using different dinuclear gold catalysts.

Based on a 16-warm-season statistical study on the mesoscale convective systems (MCSs) that were generated over the Tibetan Plateau (TP),11 long-lived eastward propagating MCSs of the same type were selected for a composite semi-idealized simulation and a
Sclerophyllous evergreen broad-leaved forests,mainly made up of sclerophyllous oak,Quercus section Hetero-balanus (Φerst.) Menitsky,Fagaceae,represent the most typical forest type in the Hengduan Mountains.Their distribution pattern is closely related to
Atmospheric refractivity fields are more strongly affected by more water vapor in the tropical lower troposphere than elsewhere.In this study,based on model simulations,we first collocated the radio occultation (RO) data in 2009 from the Constellation Obs
Hollow metal-organic frameworks (HoMOFs) as emerging materials have been arousing great interest in heterogeneous catalysis with respect to the solid counterparts,mainly because of their unique and intriguing features such as high surface to volume ratio,
Rechargeable ion batteries are one of the most reliable energy storage technologies for the applications ranging from small portable devices and electric vehicles to renewable energy integration and large-scale stationary energy storage.In the roadmap of
Rechargeable aluminum batteries (RABs) have attracted great interest as one of the most promising candidates for large-scale energy storage because of their high volumetric capacity,low cost,high safety and the abundance of aluminum.However,compared with
Following the age of directing group,anchoring catalysis starts coming to the center of the stage.Different from the directing-group strategy that needs a preinstalled directing group in substrates,anchoring catalysis relies on a reversible interaction be
China\'s Mars exploration mission has stimulated tremendous interest in planetary science exploration recently.To propose potential scientific research projects,this study presents a concept simulation for the measurement of Martian atmo-spheric winds u
Precisely analyzing the target materials in living cells can reveal the essence and mystery of life at a deeper level,which will provide reliable theoretical basis for the occurrence,development,treatment and prognosis of major diseases.However,because li
Electrocatalysis,as the nexus for energy storage and environmental remediation,requires developing low-cost and high-performing heterogeneous catalysts.Compared with the single atom catalysts (SACs),dual-atom catalysts (DACs) are attracting ever-increasin
