- 中文摘要: Various kinds of a-halo ketones readily reacted with disodium (dimercaptomethylene)malononitrile to give the corresponding 3,4-diamino-2,5-diacylthieno[2,3-b]thiophenes in good to excellent yields. The reaction was successfully extended to the synthesis of a thienothiophene derivative having two sydnone rings by using the 4-(bromoacetyl)sydnone.
