        • {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.
