Disclosed is a nonaqueous secondary battery having a nonaqueous electrolyte containing a lithium salt dissolved in an organic solvent, in which the positive electrode active material is preferably a manganese-containing, lithium transition metal oxide salt. The nonaqueous electrolyte contains at least one compound of general formula (1), preferably at least one compound of general formula (1′). The content of the compound of formula (1) or (1′) in the nonaqueous electrolyte is preferably 0.001 to 10 mass %. The symbols in formulae (1) and (1′) are as defined in the description.

carboxylic acids were transformed into their trimethylsilyl esters with HMDS in a practically completely solvent-free process, while a catalytic amount of iodine was required in some cases. The process has several advantages over the known methods: untreated reactants, air atmosphere, mild and neutral conditions, no evolution of hydrogen halide, no need of an additional base, low amount of waste, completely
