2.本文研究了在不同条件下，1-溴-1-（3，4-二甲氧基苯基）-2-丙酮和3-氯-1-（3，4-二甲氧基苯基）-2-丙酮转化为相应的醇、乙酸酯和乙醚时所伴随的烯丙基重排和歧化重排反应。3.这些重排发生的容易性为Hibbert的理论提供了有价值的证实，即来自木材的乙醇分解产物实际上是由以氧松柏醇（3，7-二氧异丁香酚）或其酮异构体为代表的类型的更具反应性的木质素前体形成的稳定的终产物，并为他关于天然木质素结构的观点提供了强有力的支持。
2. The allylic and dismutation rearrangement reactions attendant upon the conversion of the two halides, l-bromo-l-(3, 4-dimethoxy-phenyl)-2-propanone and 3-chloro-l-(3, 4-di-methoxyphenyl)-2-propanone to the correspond-ing alcohols, acetates and ethyl ethers have been studied under a variety of conditions. 3. The ease with which these rearrangements occur provides valuable confirmation of the theory of Hibbert that the ethanolysis products from wood are in reality stabilized end-products formed from more reactive lignin progenitors of the type represented by oxyconiferylalcohol (3, 7-dioxyisoeugenol) or its keto isomer, and provides strong support for his views on the structure of native lignin.
