Electron-deficient tin(IV)tetraphenylporphyrin perchlorate: A highly efficient catalyst for chemical fixation of carbon dioxide

Electron-deficient tin(IV)tetraphenylporphyrin perchlorate, [SnIV(TPP)(ClO4)2] was used as a highly efficient catalyst for chemical fixation of carbon dioxide. The bifunctional catalytic system [Sn(TPP)(ClO4)2]/tetrabutylphosphonium bromide (TBPB) was applied for preparation of cyclic carbonates from epoxides and carbon dioxide. The effect of reaction parameters was also investigated.
