determining associative coordination of diallene to form a diallene−iron complex. The effect of coordinating solvents on this cycloaddition reaction suggests that the synthetic utility of these transformations can now be expanded to include diallenes with functional groups that may only weakly coordinate to the iron. Only one sterically demanding substituent on the diallene termini is necessary to give good
