A facile synthetic protocol enables the synthesis of the 4‐phosphanyl‐5‐thiophosphanoyl thiazole‐2‐thione 1 through the selective lithiation of the 5‐thiophosphanoyl thiazole‐2‐thione VIb followed by reaction with chlorodiphenylphosphane. The reaction of 1 with elemental sulfur leads to the P V /P V homochalcogenide thiazole‐2‐thione 2 . The heterochalcogenide thiazole‐2‐thione 4 was obtained through the reaction of P III /P V ‐substituted thiazole‐2‐thione VIb with H 2 O 2 –urea. All compounds were characterized by 31 P, 1 H, and 13 C NMR spectroscopy, IR spectroscopy, elemental analysis, mass spectrometry, and single‐crystal X‐ray diffraction studies.
