  摘要：

  使用格氏试剂，通过化学选择性的C（O）-N键裂解，可将多种N-Boc酰胺转化为芳基酮。反应在无催化剂的条件下用不同的芳基，烷基和炔基格氏试剂进行。α-酮酰胺已成功转化为芳基二酮，而α，β-不饱和酰胺经过1,4-加成，然后经C（O）-N键裂解，得到二芳基丙酮。N-Boc酰胺比使用格氏试剂的Weinreb酰胺具​​有更高的反应性。广泛的底物范围，优异的产率和快速的转化是该方法的重要特征。

  Metal‐catalyzed chelation‐assisted C−H olefinations have emerged as powerful tools for the construction of functionalized alkenes. Herein, we describe the rhoda‐electrocatalyzed C−H activation/alkenylation of arenes. The olefinations of challenging electron‐poor benzamides were thus accomplished in a fully dehydrogenative fashion under electrochemical conditions, avoiding stoichiometric chemical oxidants

In this contribution, it was found that the supported lanthanum benzyl material La(CH2C6H4NMe2-o)3@SBA-15 was highly active for the hydroboration of primary, secondary, and tertiary amides to amines with pinacolborane. These reactions selectively produced target amines and showed good tolerance for functional
