WebIodomethane (Methyl iodide) has been used to generate iodide water cluster reagent ions for ToF-CIMS (time-of-flight chemical ionization mass spectrometry) analysis. It may be used to prepare (E)-1-iodopropene and N,N,N-trimethylchitosan (TMC). General description. Iodomethane also known as methyl iodide is a methylating agent. http://surface.chem.uwm.edu/pubs/Tysoe176.pdf

WebMy advice is the following: Flame dry, or at least oven dry, your glassware. Whichever carbonate you use, make sure to dehydrate it before use. Carbonate bases are hygroscopic, and so shelf-carbonate will introduce water into your reaction, consuming your methylating agent. You can dehydrate it by heating in a flask under vacuum overnight.
