Thiiranes ring opening reactions with nucleophile

Thiiranes similarly undergo ring-opening reactions with nucleophiles, such as amines, but attack at sulfur can also occur with lithium reagents. ... [Pg.595]

The progress on S-C bond activation, which covers the reduction of a C-S bond to a C-H bond, cross coupling reaction of sulfides with main group organometaUic nucleophiles, ring opening reactions of thietanes and thiiranes, and desulfurization of thiols, sulfides, and thiophenes has already been reviewed elsewhere [6-10], and... [Pg.217]

Sulfur atom as internal nucleophile. In this area, it has been shown that the reaction of 8-bromo-l,3-dimethyl-7-(2,3-epithiopropyl)xanthine 147 with a range of aliphatic and aromatic amines generates efficiently 2-amino-substituted 2,3-dihydro-thiazolo[2,3-/]xanthine derivatives 148. The process involves a sequential amine-induced thiirane ring opening followed by thiolate z/MYi-substitution of chlorine atom (Equation 66) <1994PCJ647>. [Pg.153]

The ring opening of thiiranes with an emphasis on the regiospecificity of the ringopening reaction with different nucleophiles and on the effect of such nucleophiles on the 5n reactions, alkene formation, and polymerization reactions, has been reviewed. [Pg.332]

The reaction is thought to proceed via activation of the oxirane by I2 (situation 1), followed by nucleophilic ring-opening with thiocyanate (to give 2) and subsequent formation of an oxathiolane intermediate (3) 3 undergoes rearrangement to the thiolate 4, which closes the thiirane ring by Sni displacement of cyanate ion. [Pg.28]
