Probably the most popular approach for the preparation of η5-phospholyl complexes is the reaction of phospholide ions with transition-metal salts. This approach benefits from the high aromaticity of phospholide ions and their availability. A cobaltocenium complex 77 was synthesized by this approach in 86% isolated yield from potassium phospholide 76 (Scheme 31).[‌136‌]
