Described herein is a visible‐light‐mediated atom‐transfer radical cyclization (ATRC) using 1,6‐enynes as substrates. The sulfonyl chlorides not only served as sulfonyl radical sources but also provided a chlorine atom to enable the formation of highly functionalized cyclic products. This visible‐light‐mediated photocatalytic method is a mild and practical strategy for synthesizing chloroalkyl‐substituted cyclic alkenyl sulfones.
