The capacity of the nitrogen nucleophile, 1,8-diazabicyclo(5.4.0)undec-7-ene (DBU) to reduce aryl- and heteroaryl disulfides to the corresponding mercaptans is demonstrated. While dicarboxylated disulfide analogues afford the mono-DBU disulfide salts, as confirmed by X-ray crystallography, the corresponding methyl esters are cleaved normally .
证明了氮亲核试剂 1,8-二氮杂双环 (5.4.0) undec-7-烯 (DBU) 将芳基和杂芳基二硫化物还原为相应的硫醇的能力。虽然二羧基二硫化物类似物提供了单 DBU 二硫化物盐,如 X 射线晶体学所证实的,但相应的甲酯通常会被裂解。
