36% | With polyphosphoric acid; at 170℃; for 3h; | A mixture of 4-Bromo-3-methyl-benzamide (1 g, 4.67 mmol) and vinylene carbonate (0.4 ml, 6.30 mmol) in PPA (15 ml) was heated to 170 C. for 3 h. Upon completion, the reaction was cooled, quenched with water, and extracted with EtOAc. The organic phase was washed with brine, dried over Na2SO4, and concentrated. The crude material was purified by column chromatography to give 2-(4-Bromo-3-methyl-phenyl)-oxazole (400 mg, 36%). |

55% | With palladium diacetate; caesium carbonate; triphenylphosphine; In N,N-dimethyl-formamide; at 120℃; for 1h;Inert atmosphere; | General procedure: A stirred mixture of bromobenzene (471 mg, 3.0 mmol), vinylene carbonate (86 mg, 1.0 mmol), Pd(OAc)2 (22 mg, 10 mol %), PPh3 (52 mg, 20 mol %), and Cs2CO3 (715 mg, 2.2 mmol) in DMF (1.5 mL) was heated to 120 C for 30 min under nitrogen atmosphere. After aqueous extractive workup and column chromatographic purification process (hexanes/EtOAc, 20:1) benzil was obtained as a pale yellow solid, 170 mg (81% based on vinylene carbonate), along with biphenyl (65 mg, 28% based on bromobenzene) as a white solid. |

90% | With triethylamine; at 0 - 20℃; for 1.0h;Inert atmosphere; | Vinylene carbonate (86 mg, 1 mmol) and triethylamine (10 mg, 0.1 mmol) were mixed. The system was purged with nitrogen, and <strong>[83706-98-3](Z)-4,4,4-trifluoro-2-buten-1-ol</strong> (126 mg, 1 mmol) was dropwise added at 0 C. The solution was returned to room temperature and stirred for one hour, whereby 190 mg (yield: 90%) of the target product represented by the following formula was obtained. |
