Fecha de publicación: | 2002 | Editor: | Science Reviews Limited | Citación: | Journal of Chemical Research 2002(1) : 34-36 (2002) | Resumen: | The 13C NMR spectra of the bromide of the protonated iminophosphorane-substituted sponge 7 were recorded at different fields. Together with the use of 13C satellites of the 31P NMR spectrum, these experiments allow determination of a reasonable set of chemical shifts and coupling constants. The most interesting are a 4hJPP = 1.6 Hz, determined directly from the 31P NMR spectrum, which probably involves the hydrogen bond, and a 2Δ31P(13C) isotope shift of 9 ppb. | Versión del editor: | http://www.ingentaconnect.com/content/stl/jcr/2002/00002002/00000001/art00016 | URI: | http://hdl.handle.net/10261/35131 | ISSN: | 0308-2342 |
