planar chiral heteroaryl monophosphines have been synthesised and studied. The phosphines are readily prepared from 4-imidazole[2.2]paracyclophane by selective deprotonation and reaction with the appropriate dialkylchlorophosphines. The planar chiral imidazole was constructed in four steps from readily available [2.2]paracyclophane. The 2-phosphino-N-[2.2]paracyclophanes were active in the Suzuki–Miyaura
