Chem. Samples from the vadose zone of a site contaminated with chlorobenzene (CB), 1,2-dichlorobenzene (12DCB), and 1,4-dichlorobenzene (14DCB) were packed in a multiport column to simulate the interface of the vadose zone with an underlying groundwater plume. The dithiol 1a (204 mg) and dichlorobenzene 2a (265 mg) gave 3a8 (152 mg, 48%) as a colorless oil.
