Various types of aldehydes and ketones could be converted to their corresponding diethyl acetals with triethylorthoformate in the presence of TiO2/SO42- solid superacid in good to excellent yield under mild reaction conditions.
18O-Isotope Effect in 13C Nuclear Magnetic Resonance Spectroscopy. 5 - Substituent Group Electronic Effects in Substituted Acetophenones
Risley, John M.,DeFrees, Shawn A.,Etten, Robert L. Van
, p. 28 - 35 (2007/10/02)
A series of para- and meta-substituted acetophenones were prpared which were highly labeled with 18O at the carbonyl function.The natural abundance 13C NMR spectra of the compounds were recorded and the 18O-isotope-induced shifts of the carbonyl carbon we
