supporting information, p. 10879 - 10882 (2014/10/15)
An efficient method for the synthesis of phosphoric fluoride via oxidative coupling between hydrophosphine oxide and NaF is reported. DDQ serves as the oxidizing reagent as well as the hydrogen acceptor. The process involves a Cu(ii) catalysis and exhibits great functional group tolerance under mild reaction conditions. the Partner Organisations 2014.
Determination of water content in olive oil by 31P NMR spectroscopy
Hatzakis, Emmanuel,Dais, Photis
experimental part, p. 1866 - 1872 (2009/12/07)
A method for moisture determination in olive oil using 31P NMR spectroscopy is developed. This method is based on the replacement of the hydrogen atoms of water molecules with the tagging agents 2-chloro-4,4,5,5- tetramethyl-1,3,2-dioxaphospholane and diphenylphosphinic chloride. Both reagents were successful in determining moisture in olive oil. However, only the second reagent provided a clean and instantaneous reaction under mild condition with no side reactions as observed with the first reagent. A study comparison was made to assess the agreement between the present analytical NMR method and the well-established methods of Karl Fischer titration.
