Abstract
The introduction of easy-to-handle SO2 surrogates has transformed the field of sulfur chemistry, enabling methodologies
utilizing SO2 to be carried out without specialized apparatus, and paving the way for the development
of new procedures. This review highlights some of the varied and significant developments
associated with one of the most prominent SO2 surrogates: DABSO.
