✦ Synopsis

No. 24 communication demonstrates that the Li/K-dithioate 2 corresponds to the d5-synthons 2) 1'9 i", and 4"' , Addition of carbon disulfide to homoallyl Grignard reagent and alkylation of the resulting dithioate with iodomethane or 2-iodopropane (in the presence of HMPT) furnishes the dithioesters 2 in better than 80% yield 4) . As with Y.&unsaturated ketones 3d),treatment of 5 first = with potassium hydride (O"-20°C) and then with sec_butyllithium/2 TMEDA (-78'C) in THF generates Li/K-derivatives of dianions: in as orange suspension, 4i as red-brown solution.
