Green synthesis of substituted thiazine derivatives via an efficient and novel Cobaltnanocatalyst (γ-Fe۲O۳@FAp@Co)

In this work, γ-Fe۲O۳@FAp@Co was utilized in the synthesis of polysubstituted thiazine derivativesby the reaction of verious aryl aldehydes, acetaldehyde or malononitrile, benzaldehyde and thiosemicarbazidein water at room temperature. This method provided a novel approach for the green synthesis of thiazine inexcellent yield (۸۵–۹۵%) and reasonable reaction time (۶۰–۸۰ min). The structures of prepared compoundswere confirmed by analytical methods
