The readily available, heterogeneous, and inexpensive catalyst nickel-on-charcoal (Ni/C) can be used to mediate couplings between vinyl alanes and benzylic chlorides under very mild conditions and in good yields. Although such allylated aromatics are themselves important compounds, as demonstrated in this work, their syntheses under the ‘green chemistry’ conditions used can smoothly arrive at precursors to valued quinone natural products, such as the nutraceutical coenzyme Q10.
