Herein α-bromoacrylic acids have been employed as C1 insertion units to achieve the palladium-catalyzed [4 + 1] annulation of 2-iodobiphenyls, which provides an efficient platform for the construction of diverse dibenzofulvenes. This protocol enables the formation of double C(aryl)–C(vinyl) bonds via a C(vinyl)–Br bond cleavage and decarboxylation. It is particularly noteworthy that the method features
