摘要：

An efficient and practical approach for the synthesis of triaryl allenyl sulfones from easily accessible propargylic alcohols was developed, by using sodium sulfinates as a sulfonyl source in the presence of Bronsted acid. The reaction proceeded via allenyl carbocation as the key intermediate and was followed by a nucleophilic attack of sodium sulfinates to produce allenyl sulfones in moderate to excellent yields.
