Treatment of the 1,3-diphospha(1,3)butadiene (I) with Ni(CO)4 or Fe2(CO)9 affords η1- or η4-coordination to a M(CO)3 fragment.Complex formation by the reaction of 1,4-diphospha(1,3)butadiene (IV) with C7H8M(CO)4 or M(CO)5THF (M = Cr, Mo, W) yields the doubly η1-coordinated compounds, which readily undergo E/Z-isomerization compared to IV.Bonding of a Mo(CO)4 fragment to the 1,2,4-triphospha(1,3)butadiene (VIII) was attained by two different reactions.
