“…The isotopic distribution of the envelope surrounding the molecular ion matches that expected for 5 , and there is a good agreement between the calculated mass distribution and the observed mass spectrum. The IR absorptions in the carbonyl region show a pattern similar to those recorded for alkyne butterfly clusters Os 4 (CO) 12 (μ 4 -η 2 -alkyne) …”

“…This complex consists of a tetraosmium butterfly framework bridged by a phenylbenzyne moiety. Complex 5 is the first butterfly cluster of the type [Os 4 (aryne)(CO) 12 ], although there are several alkyne complexes of this type . The ruthenium analogues Ru 4 (μ 4 -η 2 -naphthyne)(CO) 12 ] and [Ru 4 (μ 4 -η 2 -phenanthryne)(CO) 12 ] were recently reported by Deeming and Speel …”

Co-thermolysis of biphenylene ((C 6 H 4 ) 2 ) with Fe 3 (CO) 12 or Fe 2 (CO) 9 leads to activation of a biphenylene C-C bond to generate Fe 2 (CO) 5 (µ-CO)(µ-η 2 ,η 4 -(C 6 H 4 ) 2 ) (1). Similar reaction with Ru 3 (CO) 12 affords Ru 2 (CO) 5 (µ-CO)(µ-η 2 ,η 4 -(C 6 H 4 ) 2 ) (2) and Ru 6 (CO) 17 (µ 6 -C) (3), and the reaction with Os 3 (CO) 12 affords Os 2 (CO) 6 (µ-η 2 ,η 4 -(C 6 H 4)2 ) (4) and Os 4 (CO) 12 (µ 4 -η 2 -(C 6 H 3 )Ph) (5). In contrast, treating biphenylene with Os 3 (CO) 10 (NCMe) 2 leads to C-H bond activation to give (µ-H) 2 Os 3 (CO) 9 (µ 3 -η 2 -C 6 H 2 (C 6 H 4 )) ( 6). The new compounds have been characterized by elemental analyses and mass, IR, and NMR spectroscopy. The structures of 2, 4, and 5 were determined by an X-ray diffraction study. Compound 2 and 4 can be viewed to contain a metallacyclopentadienyl unit which binds the other metal atom in an η 5 -fashion. Compound 5 is the first butterfly cluster of the type Os 4 (CO) 12 (aryne).

“…Since the density of a plasma jet is always much less than that of the cold ambient air, one might anticipate that it is hard to generate a stable long laminar plasma jet in atmospheric-pressure air surroundings. Indeed, long laminar plasma jets cannot be generated by use of a conventional DC arc plasma torch employed for plasma spraying [4] or even for basic studies [5,6]. However, stable long laminar thermal plasma jets have been successfully generated in recent decades by the use of specially designed DC nontransferred arc plasma torches in atmospheric-pressure air surroundings [7][8][9].…”

Silent and stable long laminar plasma jets can be generated in a rather wide range of working parameters. The laminar flow state can be maintained even if considerable parameter fluctuations exist in the laminar plasma jet or if there is an impact of laterally injected particulate matter and its carrier gas. The attractive special features of laminar plasma jets include extremely low noise level, less entrainment of ambient air, much longer and adjustable high-temperature region length, and smaller axial gradient of plasma parameters. Modeling results show that the laminar plasma jet length increases with increasing jet inlet velocity or temperature and the effect of natural convection on laminar plasma jet characteristics can be ignored, consistent with experimental observations. The large difference between laminar and turbulent plasma jet characteristics is revealed to be due to their different laws of surrounding gas entrainment. Besides the promising applications of the laminar plasma jet to remelting and cladding strengthening of the metallic surface and to thermal barrier coating preparation, it is expected that the laminar plasma jet can become a rather ideal object for the basic studies of thermal plasma science owing to the nonexistence of the complexity caused by turbulence.

“…[5a,5b,5d, 16,19] The solvent effect for this kind of thermal reaction is partly decided by the reaction temperature. When ligand precursor 2 was treated with Ru 3 (CO) 12 in heptane at 140°C, complex 10 was also isolated, in addition to 21 and 22.…”

Reactions of the pyridyl side chain functionalized indenes 3‐R‐C9H7 [R = (C5H4N)CH2CMe2 (1), (MeC5H3N)CH2CMe2 (2), (C5H4N)CH2 (6)] with Ru3(CO)12 in refluxing xylene gave the facial coordinated indenyl cluster [μ3‐η5:η2:η2‐(C5H3N)CH2Me2C(C9H6)]Ru4(μ3‐CO)(CO)7 (8), the syn‐η5:η6‐coordinated indenyl cluster [μ‐η5:η6‐(MeC5H3N)CH2CMe2(C9H6)Ru2(CO)3]2 (10), and the η1:η2‐coordinated indenyl complex[η2‐(C5H3N)CH2(C9H7)][η1:η2‐(C5H4N)CH2(C9H6)]Ru2(CO)4(18), respectively, in addition to the normal diruthenium complexes [(η5‐RC9H6)Ru(CO)]2(μ‐CO)2 [R = (C5H4N)CH2CMe2 (7), (MeC5H3N)CH2CMe2 (9), (C5H4N)CH2 (17)]. When the pyridyl side chains were replaced by other bulky groups [R = tBu (3), PhCH2Me2C (4), (C9H6N)CH2Me2C (5)], the similar syn‐η5:η6‐coordinated indenyl clusters 12, 14, and 16 were also obtained. When 1 or 2 were treated with Ru3(CO)12 in refluxing heptane, the ionic clusters {[(C5H4N)CH2Me2C(C9H6)]Ru(CO)2}+[HRu6(CO)18]– (19), [(C5H4N)CH2Me2C(C9H8)]+[HRu6(CO)18]– (20), and complex 8 or ionic clusters {[(MeC5H3N)CH2Me2C(C9H6)]Ru(CO)2}+[HRu6(CO)18]– (21) and [(MeC5H3N)CH2Me2C(C9H8)]+[HRu6(CO)18]– (22) were obtained. Similar treatment of 5 or 6 with Ru3(CO)12 in refluxing heptane gave the ionic clusters [(C9H6N)CH2Me2C(C9H8)]+[HRu6(CO)18]– (23) or {[η3‐(C5H4N)CH(C9H7)][η2‐(C5H4N)CH2(C9H7)]Ru(CO)}+[HRu6(CO)18]– (24), respectively, in addition to complex 18 in the latter case. The molecular structures of 8, 9, 10, 14, 17, 18, 21, 22, and 24 were determined by X‐ray diffraction analysis.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
