Abstract
Titanium silicate molecular sieve, having MFI (TS-1) topology, efficie ntly catalyses the oxidative cleavage of various tosylhydrazones to th e corresponding carbonyl compounds in moderate to good yields, using d ilute hydrogen peroxide (30%) as an oxidising agent and involving a un ique electrophilic species; mechanistically, the intermediacy of oxazi ridine has been established.
