A new method for the preparation of aluminum and titanium tris(2,6-diphenylphenoxide) reagents and their application in organic synthesis
A new method for the preparation of aluminum and titanium trisphenoxides was realized using tetraallyltin or alpha-pinene as a proton-trapping agent. Thus obtained chlorotitanium reagent was converted to the corresponding cation-type reagent, which proved to be an effective catalyst for epoxide rearrangements.
