The invention provides a new cyclization reaction to obtain 4-alkenyl-2-oximino-1,3-dithiolanes by reacting a trans-or cis-1,4-dihalogeno-2-butene with a salt of a dithiocarbamic acid and further reacting the resulting intermediate product 4-alkenyl-2-imino-1,3-dithiolane in the usual way with hydroxylamine.
