  Bicymantrenyl, eta(5),eta(5)-C10H8[Mn(CO)(3)](2) (1), may be metallated at the Cp-ring with BuLi (THF, -60 degrees C) to give monolithium (2) and polylithium derivatives. Metallation of 1 proceeds concurrently on both alpha- and beta- positions, the beta-substitution product being predominant. A number of derivatives of 1 with substituents R = D, COOH, CHO, PPh2 have been synthesized in the reactions of monolithium derivative 2 with different electrophiles (D2O, CO2, DMFA, Ph2PCl respectively). Under the action of CuCl2 the oxidative coupling of 2 proceeds to give tetracymantrenyl (11a). Oxidative coupling of a mixture of 2 with cymantrenyllithium affords two isomers of tricymantrenyl (12a, 12b). The structures of 11a, 12a, 12b were established by an X-ray study.
