Boron-masking strategy for the selective synthesis of oligoarenes via iterative Suzuki-Miyaura coupling
The iterative synthesis of oligoarenes via an organoborane-based cross-coupling reaction (i.e., the Suzuki-Miyaura coupling) has been achieved by using a series of "masked" haloarylboronic acids as building blocks whose ordinarily reactive boronyl groups are temporarily protected by a new masking group derived from 1,8-diaminonaphthalene.
