Sb(V) in strong Bronsted acid solvents is traditionally assumed to react with light alkanes through superacid protonolysis, which results in carbocation intermediates, H2, and carbon oligomerization. In contrast to this general assumption, our densit

To our knowledge, there is no precedent for the direct conversion of light alkanes to aminated products by CH activation. Previous molecular systems reported for alkane amination operate by radical...

Owing to the strong nonpolar bonds involved, selective C-H functionalization of methane and ethane to esters remains a challenge for molecular homogeneous chemistry. We report that the computationally predicted main-group p-block SbV (TFA)5 complex s

The development of next-generation processes that enable the clean and economical conversion of methane to all products that are currently derived from petroleum remains a long-standing, “Grand Challenge” within the field of chemistry. The key ch

The complex Pt(IPr)(SnBut3)(H), 1 [IPr=N-heterocylic carbene ligand N,N’-bis-(2,6-(diisopropyl)phenyl)imidazol-2-ylidene] reacts with trimethylsilylacetylene to yield the C-H activation product Pt(IPr)(SnBut3)(κ1-C≡CSiMe3)(H)2, 2. Complex 2 isom

Transition metal complexes containing the sterically encumbered SnBut3 group are the focus of this brief review. The ability of tin compounds to modify both heterogeneous and homogeneous catalysts has been known for some time. Our recent efforts cent

One of the remaining “grand challenges” in chemistry is the development of a next generation, less expensive, cleaner process that can allow the vast reserves of methane from natural gas to augment or replace oil as the source of fuels and chemic

The kinetics of the reaction of Ph3SnH with excess •Cr(CO)3C5Me5 = •Cr, producing HCr and Ph3Sn–Cr, was studied in toluene solution under 2–3 atm CO pressure in the temperature range of 17–43.5 °C. It was found to obey the rate equation d[
