Prepatation process of some halogeno- substituted mononsulfides and their hydroxy-monosulfide of isothiouronium bromide equivalents as intermediates

摘要

Abstract: the invention relates to a preparation of intermediate compound has the formula (II) where R1, n have the same definition. The new compounds as well as show in the full description and protection.The number of protective elements (12), the number of shapes (3) as n integer] to R is C2-10alkenyl, C1-10alkyl, haloC1-10alkyl C1, carboxyC1-10alkyl, C2-10cycloalkyl aryl (e.g., 10alkoxycarbonylC1-10alkyl aryl (C1-10) alkyl, (phenyl (such as phenyl (Cl I C1-6alkyl amino, or (10) alkyl R2 is a halo, the method includes halogenation compound has the formula (III)
