Serpentinization of forsteritic olivine results in the inorganic synthesis of molecular hydrogen (H(2)) in ultramafic hydrothermal systems (e. g., mid-ocean ridge and forearc environments). Inorganic carbon in those hydrothermal systems may react with H(2) to produce methane (CH(4)) and other hydrocarbons or react with dissolved metal ions to form carbonate minerals. Here, we report serpentinization experiments at 200 degrees C and 300 bar demonstrating Fe(2+) being incorporated into carbonates more rapidly than Fe(2+) oxidation (and concomitant H(2) formation) leading to diminished yields of H(2) and H(2)-dependent CH(4). In addition, carbonate formation is temporally fast in carbonate oversaturated fluids. Our results …

Enantioselective Synthesis Of Bicarbocyclic Structures With An All-Carbon Quaternary Stereocenter Through Sequential Cross Metathesis And Intramolecular Rauhut-Currier Reaction, Yuan Qiao, Sanjeev Kumar, William Paul Malachowski
Chemistry Faculty Research and Scholarship
A new extension of the Birch-Cope sequence is described which allows the efficient enantioselective construction of highly functionalized, fused bicarbocyclic structures with an all-carbon quaternary stereo-center in two steps. The two-step sequence includes a cross metathesis between a terminal alkene and a polarized alkene followed by an intramolecular Rauhut-Currier reaction with a trialkylphosphine catalyst.
