Abstract
We give results for the reaction of n-butyl-lithium with triphenylmethane in benzene and in tetrahydrofuran, with triphenylethylene in tetrahydrofuran, and for the reaction of triphenylmethyl-lithium with tetrahydrofuran. The order of reaction in n-butyl-lithium is 0·5 in tetrahydrofuran as we have found previously. The results are discussed together with our earlier results, in terms of the effect of (a) solvent change, (b) change in pK of substrate, (c) change from carbon to silicon, and (d) change in steric hindrance.Keywords
