A system of logic disconnection or construction of organic molecules is given to overcome serious problems in the study of organic chemistry. Based on the logic system of polar reactions of donors and acceptors several different reactions can be created to access a required target molecule. By a following careful analysis of these proposals several transformations can be detected as the preferred ones. Moreover, by the introduction of the ''umpolung'' principle additional options are given to synthesize a required molecule. These considerations were discussed in the 1,2-, 1,3-, 1,4-, 1,5-and 1,6-difunctional series.

“…The two products, as they turned out, were the ketones (12) and (13) with no trace of the expected ene alcohol (10). The saturated ketone (12) showed in its i.r. spectrum a ketone carbonyl band at 1 710 cm-' whereas the unsaturated ketone (13) showed the same band at 1 670 cm-' besides other bands.…”
