1‐Alkenyl‐3,4,5‐triaryl‐1,2‐diphosphacyclopenta‐2,4‐dienes obtained by alkylation of sodium 3,4,5‐triaryl‐1,2‐diphosphacyclopentadienide with Br(CH 2 ) n CH=CH 2 undergo, depending on the n value, either an intermolecular Diels–Alder reaction leading to polymeric compounds ( n = 1, 4) or intramolecular cycloaddition reactions to give tricyclic cage phosphanes with high regio‐ and stereoselectivity ( n = 2, 3). The structures and conformational behavior of these new tricyclic phosphanes are discussed.
