Vanadium(IV)‐oxo Corrole Catalyzed Selective Oxidative Cleavage of Alkenes to Aldehydes

Abstract

A practical and efficient protocol for oxidative cleavage of olefinic bonds especially in arylated olefins has been demonstrated. Herein, an oxo[5,10,15‐tris(4‐nitrophenyl)corrolato]vanadium (IV) complex (cat.), has been successfully synthesized and the existence of two tautomeric forms of this complex in solution has been established. Oxo[5,10,15‐tris(4‐nitrophenyl)corrolato]vanadium (IV) (cat.) in the presence of H2O2 cleaves olefinic bonds to yield the corresponding aldehyde compounds. In general, a high valent, oxo‐(porphyrinoid)‐metal complex catalyzes the epoxide formation reactions, however, in the present case, we have observed the exclusive formation of aldehydes. The reaction offered aryl aldehydes with good yields and excellent selectivity. A mechanism was also proposed for these catalysis reactions.
