Preparation, structure, and versatile reactivity of pseudocyclic benziodoxole triflate, new hypervalent iodine reagent.
A new pseudocyclic triflate derivative of benziodoxole (IBA-OTf) was prepared and characterized by X-ray analysis. This highly electrophilic reagent readily reacts with various organic substrates to give the corresponding products in good yields. Furthermore, IBA-OTf can be used as a catalyst with m-chloroperoxybenzoic acid as the terminal oxidant.
متن کاملPseudopotential Scf-mo Studies of Hypervalent Compounds
The (ab initio) effective potential method developed previously has been applied to several molecules in order to establish a basis set and effective potential for iodine and to examine aspects of the potential surfaces of hypervalent compounds of iodine. Implied lone-pair stereochemical activity is found to agree well with experiment. Results for the structures and force constants closely rese...
متن کاملPseudopotential SCF-MO studies of hypervalent
New evidence bearing upon the anomalous properties of xenon hexafluoride has been obtained via the ab initio molecular orbital approach applied successfully to the diand tetrafluorides in paper 1. Structures of both XeFt and XeF6 are governed by a stereochemically active lone pair. In the case of the square-pyramidal cation the F .. -Xe-Feq angle calculated for the bare ion is within 2° of the ...
متن کاملEnhancing 2-iodoxybenzoic acid reactivity by exploiting a hypervalent twist.
A rearrangement of hypervalent bonds, or twisting, proves to be the rate-determining step in the 2-iodoxybenzoic acid (IBX) oxidation of alcohols. From this insight, derived from density functional theory calculations, we explain why IBX oxidizes large alcohols faster than small ones and propose a modification to the reagent predicted to make it more active.
متن کاملA square-pyramidal organochromium(V) compound.
The mononuclear, five-coordinate organochromium(V) compound [NBu(4)][CrO(C(6)F(5))(4)] (1) has been obtained as a dark red solid in moderate yield by treatment of the homoleptic organochromium(III) derivative [NBu(4)](2)[Cr(C(6)F(5))(5)] with NO[BF(4)] in CH(2)Cl(2) solution under an oxygen atmosphere. The Cr(V) centre in the [CrO(C(6)F(5))(4)](-) anion shows a square-pyramidal geometry with th...
