• The photolytic reactions of 1,3-butadiene epoxide with organomercurials

  日期：1999.10

  The photolytic reactions of 1,3-butadiene epoxide with organomercurials gave the substituted unsaturated alcohol and aldehyde as the major products in moderate yields. The substituted unsaturated alcohol was the major product in the absence of DABCO. However, the reactions gave the substituted unsaturated aldehyde as a major product in the presence of DABCO.

  1,3-丁二烯环氧化物与有机汞的光解反应以中等收率得到了取代的不饱和醇和醛为主要产物。在没有DABCO的情况下，取代的不饱和醇是主要产物。然而，该反应在DABCO存在下以取代的不饱和醛为主要产物。
