The invention relates to lithium metal/porous metal oxide compositions. These lithium metal compositions are prepared by mixing liquid lithium metal with a porous metal oxide in an inert atmosphere under exothermic conditions sufficient to absorb the liquid lithium metal into the porous metal oxide pores. The lithium metal/porous metal oxide compositions of the invention are preferably loaded with lithium metal up to about 40% by weight, with about 20% to 40% by weight being the most preferred loading. The invention also relates to lithium reagent-porous metal oxide compositions having RLi absorbed into a porous oxide. In formula RLi, R is an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an alkaryl group, or an NR1R2 group; R1 is an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an alkaryl group; and R2 is hydrogen, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, and an alkaryl group. The preparation and use of these compositions are also described. |
