有机合成,溶剂。工业上主要用于可充电锂离子电池的电解液,只能在干燥环境下使用操作(如环境水分小于20ppm的手套箱内)。
{ALF} Useful alkylating agent. Although less reactive, dimethyl carbonate has the advantage of much lower toxicity than the more usual sulfate or iodide. In the presence of K2CO3 and 18-crown-6, alcohols, phenols, thiols, imidazoles, etc. can be methylated: Synthesis, 382 (1986). For K2CO3 promoted alkylation of active methylene compounds at 180-220o (pressure), see: Rec. Trav. Chim., 115, 256 (1996); Org. Synth., 76, 169 (1998). Other dialkyl carbonates behave similarly.

{ALF} Grignard reagents react in THF to give methyl esters, providing a high-yield, one-pot synthesis of carboxylic esters from alkyl or aryl halides: Synth. Commun., 20, 3273 (1990).

{ALF} Conversion of a ketone to its methoxycarbonyl derivative has been used to change the preferred site of chlorination to the less-substituted carbon atom: Synthesis, 188 (1987):
