Methylaminodiphenylborane — Application of nB, 13C, 14N, 15N NMR
UB, 13C, 14N, 15N NM R is used to study methylaminodiphenylborane (1). Compound 1 can be regarded as a model compound for studying BN(pp)jr-, B C (pp)7r interactions, for determining the barrier to rotation about the B —N bond and for the application of natural abundance 15N NM R to boron-nitrogen chemistry. The 13C NM R of 1 shows a large splitting of the uC (para) resonances (in contrast to r...
متن کاملAccurate measurement of 13C-15N distances with solid-state NMR.
Solid-state NMR technique for measuring distances between heteronuclei in static powder samples is described. It is based on a two-dimensional single-echo scheme enhanced with adiabatic cross polarization. As an example, the results for intramolecular distances in alpha-crystalline form of glycine are presented. The measured NMR distances (13)C(alpha)-(15)N and (13)C(')-(15)N are 1.496+/-0.002 ...
متن کاملThe structure and biosynthesis of new tetrahydropyrimidine derivatives in actinomycin D producer Streptomyces parvulus. Use of 13C- and 15N-labeled L-glutamate and 13C and 15N NMR spectroscopy.
Two novel compounds, 2-methyl, 4-carboxy, 5-hydroxy-3,4,5,6-tetrahydropyrimidine (THP(A] and 2-methyl, 4-carboxy-3,4,5,6-tetrahydropyrimidine (THP(B] have been identified in the pool of Streptomyces parvulus by in vivo and in vitro studies. 13C and 15N were introduced into the compounds by feeding S. parvulus with 15N- and 13C-labeled L-glutamate. High resolution 13C and 15N NMR have been appli...
متن کاملInvestigation of zeolitic imidazolate frameworks using 13C and 15N solid-state NMR spectroscopy.
Zeolitic imidazolate frameworks (ZIFs) are a subclass of metal-organic frameworks (MOFs) with extended three-dimensional networks of transition metal nodes (bridged by rigid imidazolate linkers), with potential applications in gas storage and separation, sensing and controlled delivery of drug molecules. Here, we investigate the use of 13C and 15N solid-state NMR spectroscopy to characterise th...
متن کاملPartial NMR assignments for uniformly (13C, 15N)-enriched BPTI in the solid state.
We demonstrate that high-resolution multidimensional solid state NMR methods can be used to correlate many backbone and side chain chemical shifts for hydrated micro-crystalline U-13C,15N Basic Pancreatic Trypsin Inhibitor (BPTI), using a field strength of 800 MHz for protons, magic angle sample spinning rates of 20 kHz and proton decoupling field strengths of 140 kHz. Results from two homonucl...
