Sir: Herein we report the preparation of a previously unrealized class of reactive intermediates for organic synthesis, a-keto dianions 1 (R' = H or alkyl).' This name, suggestive of structure la, was OLI R I RFCL~~R' R~=CLIR' ... (I) While several species related to a-keto dianions have been studied,2 only one example of such an intermediate has been reported.2P Kaiser mentions that 2,4,6-trimethylacetophenone can be doubly deprotonated by n-butyl- lithium on the a- ...
