Abstract

Oxidation of the thioketone residue in the complex [Mn(CO)4{(PPh2)2C[double bond, length as m-dash]S}]+ (2) with hydrogen peroxide affords the sulfonate derivative [Mn(CO)4{(PPh2)2C(H)SO3}] (3), which shows amphoteric behaviour in reversible acid–base processes, and is easily chlorinated to give [Mn(CO)4{(PPh2)2C(Cl)SO3}] (8).
