“…Spectroscopic analysis suggested that the cyclopentene product adopted the same cis orientation as found for the molybdenum analogue, whereas the six‐ and eight‐membered‐ring products appeared to adopt the trans orientation , . A subsequent study found that the anticipated metallacyclobutane 32 could be prepared by using 2,5‐dihydrofuran . A structural study revealed that the expected cis orientation was adopted, as had been the case for cyclopentene.…”

The coordination of sigma bonding electron density to a Lewis acid was for some time largely the domain of boron hydride chemistry. Subsequently it was found that C-H bonds could undergo intramolecular coordination to metal centers, forming what are now known as "agostic bonds" and "agostic complexes". Thereafter, even the H-H bond in molecular hydrogen was found to be capable of coordination, leading to what are commonly referred to as "sigma complexes". Eventually, coordination by much more shielded C-C bonds was estab-[a] US Navy, Naval inorganic chemistry from the University of Utah in 2005, studying with Professor Richard D. Ernst. His graduate studies were focused on the synthesis and characterization of early-transition-metal organometallic cage structures and metallacyclobutanes. Many of the compounds studied in his research exhibited unique C-C agostic bonding interactions. His current areas of interest include catalysis, advanced biofuels, high-temperature thermosetting resins, and green chemistry. Richard D. Ernst is a Professor of Chemistry at the University of Utah. He received his B.S. degree in chemistry from the University of California in Berkeley in 1973 and his Ph.D. degree in inorganic chemistry from Northwestern University in 1977. His major areas of interest include organometallic chemistry, particularly of metal-pentadienyl compounds, coordination chemistry, and catalysis of the Fischer-Tropsch and Water Gas Shift reactions.

“…80 A number of intriguing nitrosyl complexes have been reported. [81][82][83][84][85] A new and improved synthetic route to WSF 4 was developed from the reaction of WF 6 and Sb 2 S 3 in anhydrous HF. 8 Tungsten sulfide tetrafluoride was characterised by Raman and 19 F NMR spectroscopy for the first time in HF solvent.…”

“…90 Cp*W(NO)(CH 2 CMe 3 ) 2 and Cp*W(NO)(CH 2 SiMe 3 )(Z 2 -CPhCH 2 ), two complexes which initiate the catalytic ring-retaining oligomerization of cyclic olefin substrates from cyclopentene to cyclooctene, have been reacted with analogous heteroatomcontaining cyclic olefins under thermolytic conditions. 83 These reactions with 2,5-dihydrofuran, 3,4-dihydro-2H-pyran, and 1,2,3,6-tetrahydropyridine do not result Scheme 1 in the formation of oligomeric organic products rather, afford organometallic complexes resulting from alternate modes of substrate reactivity, such as ringopening C-O bond cleavage and N-H activation. 83 Colloidal MoS 2 nanoparticles with diameters of less than 10 nm were prepared with a simple solvothermal method and demonstrated high efficiency in catalyzing H 2 evolution in Ru(bpy) 3 2+ -based molecular systems under visible light.…”
