Thermic conversion of benzene into 6-phenylfulvene with high yield mediated by GaP nanocrystalsElectronic supplementary information (ESI) available: MS and 13C NMR spectra of the as-prepared products. See http://www.rsc.org/suppdata/cc/b2/b208076a/
selected ferrocene derivatives were determined by X-ray diffraction analysis. The ferrocene derivatives and the ruthenium complexes were tested in vitro for their cytotoxicproperties against three cell lines derived from ovarian cancer (A2780, A2780cis, and SK-OV-3) and against non-tumour embryonic cell line HEK293 (human kidney cells). The most active ferrocene derivatives displayed cytotoxicity in submicromolar

Reaction of unsaturated fulveneendoperoxides with dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate gave saturated fulveneendoperoxides containing the 1,2-dihydropyridazine ring. Treatment of dihydropyridazine endoperoxides with water followed by phenyliodosylbis(trifluoroacetate) oxidation provided acrylic acid derivatives and dimethyl pyridazine-3,6-dicarboxylate.

The reaction of aryl-X or alkenyl-X (X=I, Br, OTf, ONf) with terminalacetylenes in the presence of a catalytic amount of Pd(OAc)2 provided the alkynylated products in good yields by using Cp∗Li (Cp∗=1,2,3,4,5-pentamethylcyclopentadienyl) as a base.
Rapid synthesis of fulvenes is achieved using pyrrolidinium/pyrrolidine buffers in anhydrous acetonitrile. Time-dependent UV–vis absorption and NMR spectroscopy reveal that the rate and yield of fulvene formation depend strongly on both the presence of acid in the medium and the choice of solvent, and they are negatively affected by water. Kinetic data have been collected for various substrates, and
