Several unique examples of phosphorus macrocycles , with PC double bonds, are obtained by a simple synthetic sequence that exploits the reactivity of 1,3,2‐diazaphosphinines with silyl‐substituted 1,4‐diynes. In addition to the synthesis of calix[3] 1 and calix[4] 2 , mixed macrocycles incorporating phosphinine, furan or thiophene units have also been prepared and structurally characterized.
