Spin-Echo (13)C NMR spectroscopy for the Analysis of Deuterated Carbon Compounds

J modulation of (13)C spin-echo signals is used to develop a strategy for the analysis of deuterated carbon compounds, with the aim to distinguish (13)C NMR signals of quaternary carbons, CH, CH2, CH3, CHD, CH2D, CHD2, CD, CD2, and CD3 groups.Three different experimental approaches are discussed: (1) spin-echo modulation by 1J without (2)H decoupling as the simplest method available; (2) spin-echo modulation by either 1J or 1J with simultaneous (1)H and (2)H decoupling ; (3) the combination of two (13)C spin-echo sequences with gated (1)H as well as (2)H decoupling finally leading to TANDEM-SEFT, a pulse sequence that provides the most general approach to the analysis of labeled carbon sites in organic molecules.
Regiodivergent DH or HD Addition to Alkenes: Deuterohydrogenation versus Hydrodeuterogenation

The regioselective and regiodivergent addition of H-D to a variety of 1,1-diarylalkenes was realized utilizing selectively deuterated dihydroaromatic compounds, which were generated by cobalt catalysis. The reaction was initiated by catalytic amounts of B
Regioselective Transfer Hydrodeuteration of Alkenes with a Hydrogen Deuteride Surrogate Using B(C6F5)3 Catalysis

A regioselective hydrodeuteration of alkenes using monodeuterated cyclohexa-1,4-dienes as surrogates for hydrogen deuteride (HD) gas is reported. The metal-free process proceeds under B(C6F5)3 catalysis presumably by deuteride abstraction to form borodeuteride [DB(C6F5)3]a and highly Br?nsted-acidic Wheland intermediates. Low catalyst loadings (2.5 mol %) are used, and the reaction proceeds at room temperature.
