Abstract

A synthetic route to C4/5-bis (phosphinoyl) imidazole-2-thiones (7d, e)(d: R1= nBu, R2= Me; e: R1= n-dodecyl, R2= Me) and C4/5-bis (thio/selenophosphinoyl) imidazole-2-thiones (8b, c),(9a, b, e) and 10a (a: R1= R2= Me; b: R1= R2= Ph, c: R1= iPr, R2= Me) is presented that employs initial C5 lithiation of mono-phosphinoyl/thiophosphinoyl substituted imidazole-2- thiones (3c–e)/(4a–c, e) followed by reaction with chlorodiphenylphosphane, leading to ...
