ed benzo[e]pyrenes, benzotetraphenes, and pyrenes. Comprehensive density functional theory studies buttress the mechanistic pathway comprising key steps like peri-C–H activation, alkyne 1,2-migratory insertion, and nucleophilic attack toward ketone, this attack being the rate-determining step. In addition, π-conjugated 1,1′-bipyrenes, potential photocatalyst pyrene-quinones, and putative n-type semiconductor
实现了掩蔽湾区选择性第一行过渡金属 Cp*Co(III) 催化的芳烃衍生酮的环 π 延伸,以提供 K 区功能化的苯并[ e ]芘、苯并四吩和芘。全面的密度泛函理论研究支持了包括关键步骤的机制途径,如peri -C-H激活、炔烃1,2-迁移插入和对酮的亲核攻击,这种攻击是速率决定步骤。此外,还获得了π-共轭1,1'-联芘、潜在的光催化剂芘醌和推定的n型半导体含氰基二苯并[ de , qr ]并四苯。
