The dianion of 6,6-diphenylfulvene obtained by reduction with lithium metal was first characterized spectroscopically. Reduction of 6-dimethylamino-6-phenylfulvene also generated its dianion whose reactions with electrophiles led to 6-phenylfulvene derivatives, demonstrating synthetic utility of fulvene dianions.
