  (CHR or CR2, R = alkyl) complexes have been extensively studied for alkylcarbene (CHR) ligands coordinated with high-valent early transition metal ions (a.k.a. Schrock carbenes or alkylidenes), yet dialkylcarbene (CR2) complexes remain less developed with bis(dialkylcarbene) species being little (if at all) explored. Herein, several group 8 metal porphyrin dialkylcarbene complexes, including Fe- and R

  烷基取代卡宾（CHR 或 CR 2，R = 烷基）配合物已被广泛研究用于与高价早期过渡金属离子（又名 Schrock 卡宾或亚烷基）配位的烷基卡宾（CHR）配体，但二烷基卡宾（CR 2）配合物仍然存在不太发达，双（二烷基卡宾）物种很少（如果有的话）被探索。本文中，几种第8族金属卟啉二烷基卡宾络合物，包括Fe-和Ru-单(二烷基卡宾)络合物[M(Por)(Ad)]( 1a,b，M=Fe，Por=卟啉二价阴离子，Ad=2-金刚烷基；合成了 2a,b , M = Ru) 和 Os-双(二烷基碳烯) 配合物 [Os(Por)(Ad) 2 ] ( 3a–c ) 并进行了晶体学表征。对它们的电子结构的详细研究表明，这些配合物本质上是低价的 M( II )-卡宾。这些配合物表现出显着的热稳定性和化学惰性，这是通过强金属卡宾共价性、超共轭性和刚性金刚形卡宾骨架的协同效应合理化的。各种光谱技术和 DFT 计算表明，二烷基卡宾

• Discrete Bridging and Terminal Copper Carbenes in Copper-Catalyzed Cyclopropanation

  The Cu(I) beta-diketiminate [Me2NN]Cu(eta(2)-ethylene) (2) catalyzes the cyclopropanation of styrene with N2CPh2 to give 1,1,2-triphenylcyclopropane in 67% yield. Addition of N2CPh2 to 2 equiv of 2 allows for the isolation of the dicopper carbene [Me2NN]Cu}(2)(mu-CPh2) (3) in which the diphenylcarbene moiety is symmetrically bound between two [Me2NN]Cu fragments (Cu-C = 1.922(4) and 1.930(4) Angstrom) with a Cu-Cu separation of 2.4635(7) Angstrom. In toluene-d(8) solution, 3 reversibly dissociates a [Me2NN]Cu fragment to give [Me2NN]Cu(toluene) and the terminal carbene [Me2NN]Cu=CPh2. Dicopper carbene 3 reacts with 3 equiv of styrene to give 1,1,2-triphenylcyclopropane and 2 equiv of [Me2NN]Cu(eta(2)-styrene) within minutes. DFT studies with simplified ligands indicate a stronger Cu-C pi-back-bonding interaction from two Cu(I) centers to the carbene acceptor orbital in a dicopper carbene than that present in a monocopper carbene. Nonetheless, the terminal carbene [Me3NN]Cu=CPh2 (8) that possesses a p-methyl group on each beta-diketiminato N-aryl ring may be isolated and exhibits a shortened Cu-C distance of 1.834(3) Angstrom. The stoichiometric cyclopropanation of styrene by 8 in 1,4-dioxane is first-order in both copper carbene 8 and styrene with activation parameters DeltaH(not similar or equal to) = 10.4(3) kcal/mol and DeltaS(not similar or equal to) = -32.3(9) cal/mol-K. In 1,4-dioxane, 8 decomposes to Ph2C=CPh2 via first-order kinetics with activation parameters DeltaH(not similar or equal to) = 21(1) kcal/mol and DeltaS(not similar or equal to) = -8(3) cal/mol-K. Arene solutions of thermally sensitive terminal carbene 8 decompose to [Me3NN]-Cu(arene), which reacts with 8 still present in solution to give the more thermally stable [Me3NN]Cu}(2)-(mu-CPh2).

  A one-pot process for the catalytic cyclopropanation of various alkenes with unsubstituted hydrazones is described. Iodosobenzene (PhIO) was found to be a competent oxidant of hydrazones to diazo compounds. Ni(OH)2 was chosen as an effective and cheap metal catalyst. The cyclopropane products can be generated efficiently (5 min–4 h) in moderate to good yields (42–91%) under mild (80 °C) and neat conditions
