I have studied that the Grignard reagent $\ce{RMgX}$ reacts with $\ce{CO2}$ to form $\ce{RCOOH}$ after acid hydrolysis. But does the same apply for sulfur dioxide?
Grignard reagents are good bases and also good nucleophiles. So the alkyl anion will attack the electron deficient carbon atom in $\ce{CO2}.$
But in the case of $\ce{SO2}$ the following conditions aren't present. First of all, sulfur is more electronegative than carbon. Secondly, sulfur has a lone pair of electrons which the carbon lacks. So this should further discourage an attack by the Grignard's alkyl anion.
So, what actually will happen when Grignards are treated with $\ce{SO2}?$
