A method for synthesizing allenylselenides has been developed using readily available propargyl carbonate and phenylselenol. The reaction is catalyzed by Ni(II) and proceeds via a migratory insertion and β-oxygen elimination mechanism. Due to the strong interaction between Se and Ni leading to catalyst deactivation, zinc salt was used to mitigate the deleterious effects of Se anions on the catalyst, thereby facilitating the successful synthesis of the target products.

Ni（II） 催化的亲核取代合成烯基硒化物


已经开发了一种合成烯基硒化物的方法，该方法使用现成的炔丙基碳酸酯和苯硒醇。该反应由 Ni（II） 催化，并通过迁移插入和 β-氧消除机制进行。由于 Se 和 Ni 之间的强相互作用导致催化剂失活，因此使用锌盐来减轻 Se 阴离子对催化剂的有害影响，从而促进目标产物的成功合成。
