主　　题：Thieno[2,3-d:5,4-d]dipyrimidine-4,5(3H,6H)dione bis-aza-Wittig reaction bisimino-phosphorane bis-carbodiimide synthesis. 

摘      要：2, 7-Diaminothieno[2, 3-d：5, 4-d]dipyrimidine-4, 5（3H, 6H）diones 4 were synthesized by a facile synthetic method, which includes bis-aza-Wittig reaction of bis-iminophosphorane 1 with aromatic isocyanate to give bis-carbodiimide 2 and subsequent reaction of 2 with various dialkylamine in the presence of solid K2CO3 or EtONa.
