| Questions And Answer | Back Directory | [Description]
Sodium methanesulfinate is an aliphatic sodium sulfinate. Conjugate addition of sodium methanesulfinate to vinyl heterocycles has been described. Cross-coupling reaction between aryl boronic acid and sodium methanesulfinate has been studied. It can be used in the preparation of alkyl methyl sulfone and methyl bis(4-tolyl)sulfoniumtrifluoromethanesulfonate. It is also employed in the synthesis of two sulfonyl type reversible addition-fragmentation transfer (RAFT) agents such as benzyl methylsulfonyldithioformate and benzyl phenylsulfonyldithioformate. Moreover, it can be used for synthesizing cyclooxygenase-2 inhibitors.

Sodium methylsulfinate can be used to synthesize cyclooxygenase-2 inhibitors. | [General Description]
Sodium methanesulfinate is an aliphatic sodium sulfinate. Conjugate addition of sodium methanesulfinate to vinyl heterocycles has been described. Cross-coupling reaction between aryl boronic acid and sodium methanesulfinate has been studied. Its stock solution was prepared from methanesulfonic acid by adding one equivalent of sodium hydroxide and diluting it to 4M. | [Synthesis]
In a four-necked flask with a thermometer, stirrer, reflux condenser tube and nitrogen protection device, 35% (mass fraction, the same hereinafter) of sodium metabisulfite solution 326g was added, nitrogen protection, stirring was turned on, heated to |
