90843-31-5, 5-Acetyl-2,3-dihydrobenzo[b]furan is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,90843-31-5
General procedure: The target thiosemicarbazones were prepared by dissolving corresponding ketone (2a-b) (0.005 mol) and appropriate thiosemicarbazide (1a-q) (0.005 mol) in ethanol containing 1-2 drops of HCl as catalyst. The reaction mixture was heated under reflux at 80 C for 2-3 h and course of the reaction was monitored by TLC. After the reaction completion,the excess solvent was evaporated under vacuum and the crystalline or amorphous product formed was filtered, washed with hot ethanol and then with diethyl ether to afford the required thiosemicarbazones (3a-u) in excellent yields. The synthesized thiosemicarbazones were further recrystallized by mixture of chloroform-ethanol (1:1). For X-ray measurements, single crystal of 3m was mounted on a MiTeGen loop with grease and examined on a Bruker D8 Venture APEX diffractometer equipped with Photon 100 CCD area detector and Oxford Cryostream cooler at 296 (2) K using graphite-monochromated Mo-Kalpharadiation (lambda=0.71073 A). Data was collected using the APEX-II software [33], integrated using SAINT [34] and corrected for absorption using a multi-scan approach (SADABS) [35]. The structure was solved using intrinsic phasing (SHELXT) [36]. Final cell constants were determined from full least squares refinement of all observed reflections. All non-H atoms were located in subsequent difference maps and refined anisotropically with SHELXL-97 [37], using full least squares refinement against F2. H-atoms were added at calculated positions and refined with a riding model. The structure has been deposited with the CCDC (CSD deposition numbers 1874544).
As the paragraph descriping shows that 90843-31-5 is playing an increasingly important role.
