22876-19-3, 5-Chlorobenzo[d]oxazole-2(3H)-thione is a benzoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Oxalyl chloride (1.20 g, 9.4 mmol) was added dropwise to a stirred suspension of 2- mercapto-5-chlorobenzoxazol (1.28 g, 6.9 mmol) in CH2C12 (37 mL) at < 20C. DMF (4.59 g, 62.8 mmol) was added dropwise. A vigorous gas formation was observed and the suspension turned into a solution halfway throughout the addition. The reaction mixture was stirred for 20 minutes. Two additional aliquots oxalyl chloride (1 : 0.20g, 1.35 mmol; 2: 0.40 g, 2.70 mmol) were added and the reaction mixture was stirred for 1.5 hours. HPLC indicated complete conversion of 2-mercapto-5-chlorobenzoxazol into 2,5- Dichlorobenzoxazol ., 22876-19-3
As the paragraph descriping shows that 22876-19-3 is playing an increasingly important role.
