Sodium thiomethoxide Chemical Properties,Uses,Production

Chemical Properties

Very faint yellowish red clear liquid


Strong nucleophile used for the synthesis of methyl aryl sulfides from halo-arenes. Alkanethiolates are efficient reagents for SN2 dealkylation of esters and aryl ethers.

Purification Methods

Dissolve the salt (10g) in EtOH (10mL) and add Et2O (100mL). Cool and collect the precipitate, wash it with Et2O and dry it in a vacuum. It is a white powder which is very soluble in EtOH and H2O. [Billmann & Jensen Bull Soc Chim Fr 3 2318 1936, Beilstein 1 III 1212.]
