PRoduct formation Cont

Fig. 10.46 (cont.) Mechanistic possibilities for the 1,4-addition of a Gilman cuprate to an a,/Lunsatitrated ketone. Part 2 shows the formation of the CuR-containing enolate (I) and its further reaction with typical electrophiles. The fact that all intermediates of this 1,4-addition are chiral, but generated in racemic form should not be overlooked consequently, the same is true of the final products J, K and L. 

High bumup of fissile material leads to a high fission product cont t in the fuel elements resulting in the formation of seminoble metal fission product alloys, which are insoluble in boiling nitric acid. The insoluble material ccmsists of mm sized metal particles of Ru, Rh, Tc, Mo, and Pd. These metal particles usually contain negligible amounts of uranium and plutonium and can be filtered as high level solid waste, HLSW.
