Abstract

An equimolar reaction of 2-hexyloxirane with carbon disulfide in hexane was run in the presence of triethylamine under 800 MPa at 100° C for 20 h, and gave 63% of 4-hexyl-1, 3- dithiolan-2-one (3a), 21% of 4-hexyl-1, 3-dithiolane-2-thione (1a) and 5% of 5-hexyl-1, 3- oxathiolan-2-one (4a). Hexane, benzene, and diisopropyl ether were good solvents for the reaction. The reaction of a variety of oxiranes with carbon disulfide produced 1, 3-dithiolan ...
