Abstract
The reaction of the 5,5′-bis(formyl)-2,2′-biphosphole 1 with the o-xylylidene bis-ylide 2 affords the 24-membered tetraphosphole macrocycle 3 in 60% yield; the X-ray crystal structure of 3 shows an all-trans disposition of the four lone pairs and a diameter of the central cavity of ca.6Å.Keywords
