Titanium silicate molecular sieve (TS-1) induced catalytic cleavage of tosylhydrazones

Abstract

Titanium silicate molecular sieve, having MFI (TS-1) topology, efficiently catalyses the oxidative cleavage of various tosylhydrazones to the corresponding carbonyl compounds in moderate to good yields, using dilute hydrogen peroxide (30%) as an oxidising agent and involving a unique electrophilic species; mechanistically, the intermediacy of oxaziridine has been established.
