A facile and efficient visible-light-driven method has been developed to construct sulfoxides via oxidative coupling of aryldiazo sulfones with thiols using the O 2 in air as the oxidant. This reaction could be performed at room temperature under catalyst- and additive-free conditions. The present m...
