Programmable amine synthesis is realized through sequential insertion of nitrogen and carbon atoms into boronate C−B bonds. This strategy is enabled by a new nitrenoid reagent, which allows for direct formation of aminoboranes from aryl or alkyl boronates via N-insertion.

α,β-Unsaturated acylsilanes have multifunctional sites and can be used in many transformations. However, the existing methods for preparing them generally suffer from problems, such as low atom and step economy, a narrow substrate scope, etc. Herein, an efficient and general method for accessing α,β-unsaturated acylsilanes through Ru-catalyzed cross-metathesis has been developed. This method is applied
