Abstract
Summary The 13C-NMR. spectra of thirteen lithiated hydrocarbons (lc-13 c, Table 2) and of eighteen a-halo-lithium carbenoids (14 c-31c, Table 3) have been recorded in donor solvent (R20, R3N) mixtures at temperatures down to-150". The organolithium species were generated from singly or doubly 13C-labelled precursors by H/6Li-or Br/6Li-exchange.-13C, 6Li-Coupling was observed of all species but those which supposedly contain contact ion ...
