An Isolable Terminal Imido Complex of Platinum

Yuanhang Li, Wei Li, Boyu Liu, Dongyang Wang et autres

Abstract Late transition-metal imido species serve as key intermediates in a variety of catalytic transformations. However, their transient nature renders isolation challenging, and an isolable platinum terminal imido complex has remained elusive to date. In this work, we present a platinum terminal …

Mononuclear Palladium(I) Halides Stabilized by Bis(di- tert -butylphosphino)ferrocene Ligand

Wei Li, Wooyeol Ryu, Tianqi Xia, Xiang‐Yu Wang et autres

Many radical-involving palladium-catalyzed organic transformations are proposed to proceed via mononuclear palladium(I) halide intermediates. However, isolable palladium(I) complexes of this type remain elusive, casting doubt on these mechanistic hypotheses. In this work, we demonstrate that using the bulky bisphosphine ligand bis(di- tert …

An ECEC Mechanism via an Electrophilic Co(II) Carbene in Reductive Cyclopropanation

Bin Cao, Hao‐Dong Tan, Guixia Liu, Xuebing Leng et autres

Metal carbenes have long been recognized as a pivotal reactive intermediate in organometallic chemistry. Recently catalytic reductive processes with gem -dichloroalkanes have emerged as a promising strategy to generate nonstabilized donor carbenes for alkene cyclopropanation. However, the catalytic cycle remains challenging to …

A Three-Coordinate Cobalt(-I) Dinitrogen Complex

Qing Liu, Xuebing Leng, Liang Deng

While most reported Co(-I) complexes are coordinatively saturated, we report herein a 16e – Co(-I) complex [(cyIDep)Co(η 2 -vtms)(N 2 )Na(OEt 2 )] 2 (where cyIDep = 1,3-di(2′,6′-diethylphenyl)-4,5-(CH 2 ) 4 -imidazol-2-ylidene; and vtms = vinyltrimethylsilane). The Co(-I) complex is isolated from …

Cooperative Optimization Strategy for the Electrical and Mechanical Properties of Silicone Rubber Composites During Aging

Guanyue Sun, Richang Xian, Xuebing Leng, Kai Wei

ABSTRACT Silicone rubber (SR) composite materials used for high‐voltage cable intermediate connections exhibit significant performance degradation during aging. To enhance the operational stability of SR composite materials, this paper proposes an “electromechanical” synergistic control approach, combining experimental and simulation methods to systematically …

Reactions of a Palladium(I) Amido Complex with Organic Halides

Yuanhang Li, Jian Liu, Xuebing Leng, Dongyang Wang et autres

Structurally well‐defined mononuclear Pd(I) complexes are exceedingly rare and their reactivity remains poorly understood. Herein, the reactivity of the Pd(I) amido complex [(BINAP)Pd(NHAr Trip )] ( 1 , BINAP = 2,2′‐bis(diphenylphosphino)‐1,1′‐binaphthalene, Ar Trip = 2,6‐bis(2′,4′,6′‐triisopropylphenyl)phenyl) toward organic halides has been investigated. Complex …
