Abstract As a continuation of recent study on the synthesis of a bis [1,4]oxathiinodipyridine ring system, we would now like to report the preparation of 7‐chlorobenzo[1″,2″:5,6:3″,4″:5′,6′]‐ bis [1,4]oxathiino[3,2‐ b : 3′,2′‐ b ]dipyridine. Although a potentially complex reaction with several products possible, the title compound was formed exclusively, suggesting considerable mechanistic selectivity. The characterization of the product by FT‐ 1 H‐nmr as well as its mass spectral fragmentation pathways are also reported.
