The chemistry of the carbon-transition metal double and triple bond: annual survey covering the year 1997

High-Energy Organometallic Chemistry of Curium: Laser Ablation of Cm7O12 Dispersed in Polyimide

“…Among the few isolated transuranic σ-bonded organoactinides is Cp 3 Np( n -C 4 H 9 ). In contrast to the case for the d-block transition metals, actinide carbene (alkylidene) and carbyne (alkylidyne) chemistry represents virgin territory. In the Transuranium Research Laboratory at Oak Ridge National Laboratory (ORNL), we have employed a technique to prepare a variety of gas-phase organometallic species which incorporate unique types of actinide−carbon bonding.…”

Coordinating Tectons: Bipyridyl Terminated Allenylidene Complexes

“…These molecules often owe their existence to coordination to the metal centers which stabilize them sufficiently for characterization. The allenylidene complexes have been studied less than the C 1 and C 2 homologues, although the literature has been extensively reviewed over recent years with annual surveys, [17][18][19][20][21][22] allenylidenes and higher cumulenylidenes reviewed in detail, 23,24 polymetallic C n systems, 25 C 3-5 ruthenium cumulenylidenes, 26 iridium cumulenylidenes, 27 and rhodium allenylidenes 28 being the most relevant. The seminal contributions of Selegue 29 and Berke 30 provided the first examples and, in the case of the former, a general route to these compounds.…”

Photophysics of tungsten–benzylidyne complexes derived from s-indacene: synthesis, characterization and DFT studies

“…Transition metal-alkylidynes, also known as metal-carbyne complexes [1][2][3][4] have been extensively studied over nearly four decades since their discovery. 5 Much of the interest in these compounds has been focused upon their diverse and fascinating reactivity, specially the catalytic metathesis of alkynes; [6][7][8][9][10][11][12][13][14] although many other aspects of their chemistry have also been explored, including the luminescence properties of their electronic states where the excited-state electron-transfer reactions of transition metal chromophores are integral to homogeneous systems for articial photosynthesis, dye-sensitized solar cells, and photoredox-based methods for organic synthesis, among other applications [15][16][17][18][19][20][21][22][23][24][25][26][27] and their utility as building blocks for electronic materials.…”
