Biomimetic Vanadium Complexes and Oxo Transfer Catalysis

摘要

Chiral allylamino-diethanols H2L, prepared from allylamine and styreneoxide, react with VO(O/Pr)3 to form trigonal-bipyramidal complexes of composition [VO(OMe)L] The complexes model the structure of the active center of vanadate-dependent haloperoxidases, and they also model the sulfideperoxidase activity of these enzymes. Reaction of H2L with NaH/CH3I yields (CH3)2L, which forms chloro-{bis(oxyphenylethyl)propylamine}silicate with HSiCl3.
