synthesis of a variety of planarchiraltriazole-basedphosphanes. These molecules have been readily prepared from 4-azido[2.2]paracyclophane in two steps. It was observed that the stability of the resulting phosphanes was dependent on the C-4 substituent. The efficacy of the new phosphanes in the palladium-mediated Suzuki–Miyaura couplingreaction was evaluated. The phosphanes proved to be more effective
