Nicholas reactions of the p-phenyl linked bis(propargyl acetate) complex (3a) with electron rich arenes give cyclophanetetrayne complexes (5). The use of bis( propargyl ether) complex (8) with (3a) allows formation of a mixed cyclophanetetrayne complex (9), and in addition gives retroNicholas/ intramolecular Nicholas reaction product (2).
