The reaction of M(eta/sup 5/-(CH/sub 3/)/sub 5/C/sub 5/)/sub 2/(CH/sub 3/)/sub 2/ and M(eta/sup 5/-(CH/sub 3/)/sub 5/C/sub 5/)/sub 2/(CD/sub 3/)/sub 2/ compounds, M = Th and U, with partially dehydroxylated and nearly completely dehydroxylated alumina yields methane via protolysis by surface OH, ring H atom abstraction, and elimination within the M(CH/sub 3/)/sub 2/ groups. The latter pathway is proposed on the basis of chemical evidence to result in alumina-stabilized actinide alkylidenes. 12 references, 2 tables.
