Ernst, Ludger published the artcile< Carbon-13 NMR spectroscopy of diethyl alkyl- and benzyl-phosphonates. A study of phosphorus-carbon spin-spin coupling constants over one to seven bonds>, Formula: C19H34O2, the main research area is phosphonate phosphorus carbon spin coupling; NMR phosphonate.
13C chem. shifts and 31P-13C coupling constants are reported for 10 alkyl-, 20 benzyl-, and 3 (naphthylmethyl)phosphonates. In saturated aliphatic chains 31P-13C couplings over >4 bonds could not be resolved whereas in benzyl type systems couplings over 7 bonds were observed Conformational and substituent effects on the coupling constants are discussed. NJ31P-19F (n = 4-6) are reported for the isomeric (fluorobenzyl)phosphonates and nJ31P-31P (n = 5-7) for the isomeric C6H4[CH2P(O)(OEt)2]2 (I) were obtained from 13C satellites. The relative signs of nJ31P-13C (n = 2-6) were obtained by comparison of the 13C absorptions of I (representing X of an ABX or AA’X system) with the spectra of MeC6H4CH2P(O)(OEt)2.
Organic Magnetic Resonance published new progress about NMR (nuclear magnetic resonance). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Formula: C19H34O2.
