At the Langdu skarn copper deposit, carbon and oxygen isotope ratios of fresh limestones (δ18O = 3.0–5.6 ‰ relative to V-SMOW; δ13C = 24.5–25.7 ‰ relative to PDB) and partly altered limestones (δ18O = 27–7.2 to −1.9 ‰; δ13C = 11.8–...
Carbon–oxygen bonds are commonplace in organic molecules, including chiral bioactive compounds; therefore, the development of methods for their construction with simultaneous control of stereoselectivity is an important objective in synthesis. The Williamson ether synthesis, first reported in 18501, is the...
