Old wisdom teaches a new lesson: The rate constant for the isomerization of thermally generated triphenylmethoxyl to Ph2(PhO)C. has been determined both experimentally and by DFT calculations (see scheme), and the results vindicated Wieland′s 1911 observations and conclusions—in contrast to photochemically based findings.
古老的教训传授了新的教训:将热生成的三苯基甲氧基异构化为Ph 2(PhO)C的速率常数。通过实验和DFT计算(见方案)确定了这一结果,与基于光化学的发现相反,该结果证明了Wieland在1911年的观察和结论。
