Reference of 496-46-8, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 496-46-8, name is Tetrahydroimidazo[4,5-d]imidazole-2,5(1H,3H)-dione, This compound has unique chemical properties. The synthetic route is as follows.
Example 2: Synthesis of cucurbituril homologues; [27] 3 g of paraformaldehyde was added to 5.68g of glycolurils of formula 9 and 20 mL of a 9M sulfuric acid was added thereto. Then, a 800W microwave was irradiated to the reaction mixture for 45 seconds. [28] The reaction solution was recrystallized with acetone and methanol to thereby synthesize and separate four cucurbituril homologues, CB[5], CB[6], CB[7], and CB[8 ], as represented by formula 1 where X is 0, Rand R are H, and n is 5,6, 7, and 8, respectively. The yields of CB[5], CB[6], CB[7], and CB[8] were 15%, 45%, 20%, and 15%, respectively. [29] CB [5]:¹ H (500 MHz, D 2O/CF CO DID SO 4 (1:1:0.15)): No. 4.43 (d, J = 15.5 Hz, 10H), 5.65 (s, 10H), 5.85 (d, J =15.5 Hz, lOH). [30] CB [6]:¹ H (500 MHz, D 2 O/CF 3CO2 DID 2 SO 4 (1: 1:0.15)): No. 4.35 (d, J = 15.5 Hz, 12H), 5.61 (s, 12H), 5.69 (d, J =15.5 Hz, 12H). [31] CB [7]:¹ H (500 MHz, D 2 O/CF 3CO2 DID 2 SO 4 (1: 1:0.15)): No. 4.29 (d, J = 15.5 Hz, 14H), 5.60 (s, 14H), 5.91 (d, J =15.5 Hz, 14H). [32] CB [8]:¹ H (500 MHz, D 2 O/CF 3CO2 DID 2 SO 4 (1: 1:0.15)): No. 4.28 (d, J = 15.5 Hz, 16H), 5.60 (s, 16H), 5.93 (d, J =15.5 Hz, 16H).
The chemical industry reduces the impact on the environment during synthesis Tetrahydroimidazo[4,5-d]imidazole-2,5(1H,3H)-dione. I believe this compound will play a more active role in future production and life.
