  The reaction of α-phenethyl radicals with 1,4-benzoquinone and 2,6-di-tert-butyl-1,4-benzoquinone

  摘要：

  The absolute rate constant for 1,4-benzoquinone (BQ) irreversibly trapping alpha-phenethyl radicals (3) has been determined as 4.4 x 10(6) M-1 s(-1) 43 degrees C using acyclic cis azoalkane 9c as a radical precursor. These reactants afford the hydroquinone mono ether 4 at 30 degrees C but a mixture of products at elevated temperature. 2,6-Di-tert-butyl-1,4-benzoquinone (DTBQ) also reacts with 3 but the cyclohexadienone products are thermally labile.
