Abstrakt: The Staudinger reaction between bis(azides) and bis(phosphines) under mild conditions provides macrocyclic bis(iminophosphoranes) (at least 12-membered rings) in excellent to moderate yield. The method also allows the incorporation of a heteroatom into the chain connecting the two aromatic or heteroaromatic rings.
