摘要

烯丙酸酯是一种多功能的合成材料，但其光催化转化仍未得到充分探索，主要依赖于贵金属催化剂。在此，我们报道了一种温和的，不含贵金属的光催化体系，使用4CzIPN作为光催化剂，使Het/ ar取代的叔胺在可见光驱动下高效地添加了烯丙酸盐。该协议具有衬底范围广、原子经济性高等特点。进一步阐明了反应的选择性机理，为选择性烯丙酸官能化开辟了新的途径。

Metal-free, visible light activation of 4CzIPN for the radical addition of aminoalkyl radicals to allenoates.

Allenoates are versatile synthetic building blocks, yet their photocatalytic transformations remain underexplored and mostly rely on precious metal catalysts. Herein, we report a mild, noble-metal-free photocatalytic system using 4CzIPN as the photocatalyst, enabling efficient visible-light-driven addition of allenoates with Het/Ar-substituted tertiary amines. This protocol features broad substrate scope and high atom economy. Moreover, it clarifies the reaction selectivity mechanism, opening a new avenue for selective allenoate functionalization.
