Dalton Trans., 2016, 45,2955-2962
DOI: 10.1039/C5DT03662C, PaperI. Begum, G. Schnakenburg, R. Streubel
Regioselective synthesis of the P(III) substituted thiazole-2-thione I is presented. Oxidation of I resulted in P(V) chalcogenide thiazole-2-thiones (E = O, S, Se). Desulfurization of I (E = O) using hydrogenperoxide led to the first C-phosphanoyl thiazolium salt II. Deprotonation of II and reaction with cyclooctadiene rhodium(I) chloride dimer yielded thiazole-2-ylidene rhodium(I) complex III.
