ω-Substituted alkanes and 1-hydroxyalkanes |
| abstract |
Straight- and branched-chain alkanes and 1-hydroxyalkanes of 4 to 18 carbon atoms, substituted in the ω-position by hetero-cyclic groups having the formula: wherein X is a methine group or a nitrogen atom and Y is oxygen or sulfur are prepared by reacting a haloalkane or a haloalkanol with an alkali metal salt of a compound containing the desired heterocyclic group, such as a pyridone or a substituted pyrimidine. The compounds have been found to be useful in accelerating the dark adaptation, as determined in tests with mice. |
