The following derivatives of uranocene, di-eta/sup 8/-cyclooctatetraeneuranium, U(C/sub 8/H/sub 7/R)/sub 2/, R = H (1), are described: R = OCH/sub 3/ (2), OCH/sub 2/CH/sub 3/ (3), OC(CH/sub 3/)/sub 3/ (4), OCH/sub 2/CH = CH/sub 2/ (5), N(CH/sub 3/)/sub 2/ (6), CH/sub 2/N(CH/sub 3/)/sub 2/ (7), (CH/sub 2/)/sub 3/N(CH/sub 3/)/sub 2/ (8), N/sup +/ (CH/sub 3/)/sub 3/I/sup -/ (9), CH/sub 2/N/sup +/(CH/sub 3/)/sub 3/I/sup -/ (10). Thermal Claisen rearrangement of the allyloxy compound 5 has not been observed. The ether 2 and ammonium salt 9 react with alkylithium reagents to give the corresponding dialkyluranocene apparently by a metalation chain reaction involving a cyclooctatrienyneuranium intermediate. Internal coordination of uranium by nitrogen in 7 and 8 is not significant.
