| Sodium thiomethoxide Usage And Synthesis |
| Chemical Properties | Very faint yellowish red clear liquid |
| Uses | Sodium thiomethoxide is a 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. |
| Uses | Used to prepare a C-21 thioether of methyl 16-prednisolonecarboxylate by mesylate displacement. |
| 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.] |
