Abstract
A four-step sequence allows us to transform 1-phenyl-3,4-dimethylphosphole- 2-carboxaldehyde (1) into the bis(phosphole) 5 with a CH2CH2 bridge between the two a-carbons. The cleavage of the two P-phenyl bonds of 5 by lithium, followed by the reaction of the bis(phospholide) thus formed with FeCl2, g ives the corresponding 1,1 ' -diphospha[2]ferrocenophane 7, which displays a tilt angle of 20 degrees.
