With the values of 6Li T1 measured and the literature values of J(13C-6Li) for these compounds, three new 13C NMR techniques are developed for the analysis of organolithium compounds. Modifications to the spectrometer are discussed, as well as calibrations of the 6Li decoupler channel needed to set up these new experiments. The theoretical development of each technique is presented, as well as data from their verification, using organolithium compounds of known structure. Once qualified, the new experimental techniques are used to analyze a series of alkyllithium / lithium alkoxide mixed aggregates in solution, where structures and values of J(13C-6Li) may …

With the values of 6Li T1 measured and the literature values of J(13C-6Li) for these compounds, three new 13C NMR techniques are developed for the analysis of organolithium compounds. Modifications to the spectrometer are discussed, as well as calibrations of the 6Li decoupler channel needed to set up these new experiments. The theoretical development of each technique is presented, as well as data from their verification, using organolithium compounds of known structure. Once qualified, the new experimental techniques are used to analyze a series of alkyllithium / lithium alkoxide mixed aggregates in solution, where structures and values of J(13C-6Li) may not be known. The combination of Ti relaxation measurements and 13C{1H, 6Li} triple resonance techniques serves as a means of determining the structure of organolithium aggregates in solution.
