55Mn-NMR

Mn nmr spectroscopy the authors concluded that the crown ether-separated ion pair prevails in solution. At 25°C, the complex reacts slowly (half life 48 h) with benzene. The complex reacts readily with olefins to give the potassium salts of the corresponding acids in high yields. The authors proposed a mechanism, in which the first step is a [2 + 4] electrocyclic addition as...

MHz (55Mn). For 1H MRI experiments, a 25-mm birdcage rf insert was used. For other nuclei, the broadband rf probe supplied with the instrument for high resolution NMR spectroscopy with a saddle-shaped rf coil (6-mm inside diameter) was used with the external aluminum shield removed.
