Conclusions
-
1.
Conditions were found for the alkylation of tetrahydropyran with alkenes in presence of di-t-butyl peroxide.
-
2.
The effect of reaction time and amount of the peroxide on the yield of the monoalkyl derivative was determined. The maximum yield of 2-ethyltetrahydropyran is obtained in presence of 4.4 mol.% of the peroxide.
-
3.
The six-membered cyclic ether tetrahydropyran is less reactive than its five-membered analog, tetrahydrofuran.
