Reaction Conditions:
with copper(I) bromide;lithium bromide in tetrahydrofuran at 160; for 6 h;Product distribution / selectivity;
Steps:
11
The above reaction was repeated but using acetic acid, acetonitrile or tetrahydrofuran instead of benzonitrile at various concentrations (0.02, 0.04, 0.1 and 1 ml/mmol). Table 14 shows the results, from which it may be seen that the optimal concentration depends upon the solvent, and that the best results were obtained at high concentration.
