Chloroform is said to react violently with both metals (Al, Na, Li, Mg, K, Fe, Zn) and e.g. sodium methoxide (CH3ONa). Does anyone know more about this? What happens? Formation of e.g. CCl3Na with release of H2? Or CHCl2Na+NaCl? And how about reaction with alkoxides? Does chloroform react with many of the alkoxides or mainly with alkali metal methoxides? Otherwise, it doesn't seem as a smart choice for NMR solvent if one wants to do NMR on alkoxides... Thank you for your answers.
