How does SO2Cl2 react with alcohols? Is the mechanism similar to the reaction of $\ce{SOCl2}$ with alcohols?
If not, then how is it different? We have been taught about the latter at school but my friend quizzed me about $\ce{SO2Cl2}$. 

Please give the detailed reaction mechanism.
According to this article a mixture of products is formed, with alkylchlorsulfonates $\ce{Cl-SO2-O-R}$ being dominant products. These molecules are resistant to abstraction of sulfur trioxide, probably because trioxide is a very strong Lewis acid, unlike dioxide.
