1,2,3-Benzotriazin-4(3H)-ones reacted with internal and terminal alkynes in the presence of a nickel(0)/phosphine catalyst to give a wide range of substituted 1(2H)-isoquinolones in high yield. The reaction proceeded through denitrogenative activation of the triazinone moiety and the following insertion of alkynes.
在镍(0)/膦催化剂存在下,1,2,3-苯并三嗪-4(3H)-与内部和末端炔烃反应,以高收率得到各种取代的1(2H)-异喹诺酮。该反应通过三嗪酮部分的脱氮活化和随后的炔烃的插入而进行。
