<p>The invention relates to novel compounds having the formula …<CHEM>… in which R is alkyl, cycloalkyl, aralkyl, chlorophenyl or chlorbenzyl, R1 is hydrogen or lower alkyl and n is an integer from 1 to 3. Said thiocarbonates are available by reacting the corresponding pyridyl alkanole with a chlorothioformate having the formula ……RS@Cl… at 0 - 25 DEG C in the presence of a solvent and a hydrogen chloride acceptor. The thiocarbonates of the above formula show significant insect repellent activity. They are adapted for ready use in corresponding compositions.</p> |
