  Efficient synthesis of β, β’-dihydroxy sulfides by ring opening of epoxides with mercaptoethanol catalyzed under solvent-free conditions

  摘要：

  A simple and highly efficient synthesis of beta, beta'-dihydroxy sulfides has been achieved by ring opening of epoxides with mercaptoethanol using catalytic amount of benzyltrimethylammonium hydroxide (Triton B) under solvent-free conditions. Excellent regioselectivity was found for aliphatic unsymmetrical epoxides, with nucleophilic attack at the less-hindered carbon atom of the epoxide. However, this regioselectivitywas not observed for styrene oxide and a mixture of two isomers was obtained. This process was also regio- and chemo-selective as illustrated using epichlorohydrin with two epoxide ring positions and mercaptoethanol with two functional groups (SH and OH).[GRAPHICS].1a-e 2ae(1)(alpha) 2e(2)(beta)R = CH3(a) ; C2H3(b) ; CICH2(c) ; PhOCH2(d) ; ph(e).

  Polyglycidyl epoxy resins are modified to have a blocked isocyanate moiety bound to the resin backbone through an oxazolidone ring by reacting the epoxy resin with an asymmetrically blocked diisocyanate. Further reaction with a cationic active hydrogen compound gives a modified epoxy resin having a cationic group in addition to the blocked isocyanate moieties. The modified epoxy resins are incorporated into cathodic electrodeposition paint as a crosslinker or cationic binder resin or pigment dispersing agent.
