    • The low yield is probably due to the low reactivity of 1-chloroanthraquinone 4a, because quenching experiments of 3a with methyl iodide under the same reaction conditions delivered 1-methoxy-6-(tetrahydropyran-2-yloxy)hexane in 80% yield.

    • Becher has shown that a very weak charge-transfer absorption in the UV spectrum could only be observed after keeping a solution of the donor acceptor complex for several days. See ref. 35 for details.
