Studies on the rearrangement of benzil (1) to benzilic acid (2) in the presence of caustic alkalis (M+OH−) reveal that the transformation is triggered by 1-M+ coordination and is propagated by a nucleophilic attack of OH− on the M+-complexed 1. Solid 1-M+OH− complexes can be...
In 1838 von Liebig1 described the hydroxide ion induced transformation of an α-diketone, benzil (1), into the salt of an α-hydroxy acid, benzilic acid (2; equation 1). This process is probably the first molecular rearrangement reaction to be recognized, and hence occupies a special place...
产业：是指由提供相近产品或服务、在相同或相关价值链上活动的企业所构成的企业集合。产业是与社会生产力的发展水平相适应的社会分工的表现形式。产业的形成从分工而来。产业是社会分工的产物，也是社会生产力发展的必然结果；产业形成是多层次的，随着生产力水平的不断提高，产业的内涵不断充实，外延也将不断拓展。...
Cyclization of 114 via an entropy favored electrophilic process gives an intermediate 115, which loses a second mole of acetic acid to yield quinoxaline N-oxide 112 〈06TL4969〉. The probable mechanism for the conversion of N,S-acetals 116 into quinoxalines 117 involves the initial formation ...
