Isothiazole react with hexacarbonyls

Isothiazoles react with hexacarbonyls M(CO)6 to give A-coordinated M(CO)s derivatives. 

Despite the weak basicity of isoxazoles, complexes of the parent methyl and phenyl derivatives with numerous metal ions such as copper, zinc, cobalt, etc. have been described (79AHC(25)147). Many transition metal cations form complexes with imidazoles the coordination number is four to six (70AHC(12)103). The chemistry of pyrazole complexes has been especially well studied and coordination compounds are known with thiazoles and 1,2,4-triazoles. Tetrazole anions also form good ligands for heavy metals (77AHC(21)323). Isothiazoles react with hexacarbonyls M(CO)6 to give iV-coordinate M(CO)5 derivatives.
