Structure and reactivity of a planar chiral naphthylferrocenylcopper heteroaggregate

A chiral 2-naphthylferrocenylcopper heteroaggregate (2) was prepared in high yield by reaction of (Sp-2-naphthylferrocenyl)trimethyltin with (C6F5Cu)4 and fully characterized by multinuclear NMR, single crystal X-ray diffraction, and elemental analysis. The reactivity of 2 toward boron halides was examined. Rearrangement reactions resulted in formation of 1,2-, 1,3-, and 1,1′-disubstituted naphthylferrocenylboranes.
