Selective heteronuclear INADEQUATE as an assignment technique: Applications to ²⁹Si‐¹³C couplings in pertrimethylsilylated products

Abstract

Abstract A selective heteronuclear version of the INADEQUATE experiment is described in detail. This technique allows the assignment of NMR lines of nuclei that are scalar coupled to other nuclei which can be assigned by a routine technique. The feasibility of this approach is demonstrated by the assignment of the 29 Si NMR lines in two pertrimethylsilylated monosaccharides. In this particular case, the selective heteronuclear INADEQUATE experiment was used to determine two‐ and three‐bond 29 Si‐ 13 C couplings and to assign the 29 Si lines.
