  伯酰胺对胺或腈的作用：单一催化剂的双重作用†

  摘要：

  我们报道了锰催化的各种伯酰胺向胺的加氢甲硅烷基化还原（25个例子）。通过简单地改变反应条件，例如在催化量的仲酰胺存在下，相同的催化剂就能以优异的收率将伯酰胺转化为中间体腈化合物（16个实例）。这是第一个实例，其中已经证明了用单一催化剂将伯酰胺控制地催化转化为胺或腈。

  Quantitative structure-activity analysis of larvicidal 1-(substituted benzoyl)-2-benzoyl-1-tert-butylhydrazines againstChilo suppressalis

  摘要：

  AbstractThe larvicidal activity of a number of 1‐(substituted benzoyl)‐2‐benzoyl–1 ‐ten‐butylhydrazines against the rice stem borer (Chilo suppressalis Walk.) was measured. Variations in the activity were examined quantitatively using physico‐chemical substituent and molecular parameters and regression analysis. The results indicated that the molecular hydrophobicity and the electron‐withdrawing inductive/ field effect of ontho substituents are favourable to larvicidal activity. The bulkiness of substituents at the meta and para positions was unfavourable to activity, substitution at the para position being more unfavourable than that at the meta position in terms of van der Waals' volume. The 2,3–, 2,5‐ and 2,6‐disubstitution patterns were also unfavourable to activity. Reductions in larvicidal activity caused by the 2,6‐,‐ 2,3,5‐ and 2,3,4,5‐substitutions were greater than those induced by the 2,3‐ and 2,5‐disubstitutions. When the sum of contributions from favourable effects is greater than that from unfavourable effects, the larvicidal activity is expected to be superior to that of the unsubstituted compound.

  日期：——

  potassium complex was used as a transition metal-free catalyst for reduction of primary amides to corresponding primary amines under ambient conditions. Only 2 mol% loading of the catalyst exhibits a broad substrate scope including aromatic, aliphatic and heterocyclic primary amides with excellent functional group tolerance. This method was applicable for reduction of chiral amides and utilized for the synthesis
