I found the field of Chemistry very interesting. Saw the article An Improved N-Acylation of 1 H -Benzotriazole Using 2,2-Dipyridyldisulfide and Triphenylphosphine published in 2019. Recommanded Product: 385-00-2, Reprint Addresses Tiwari, VK (corresponding author), Banaras Hindu Univ, Dept Chem, Inst Sci, Varanasi 221005, Uttar Pradesh, India.. The CAS is 385-00-2. Through research, I have a further understanding and discovery of 2,6-Difluorobenzoic acid
A novel path has been developed for the conversion of carboxylic acids into the corresponding N -acylbenzotriazoles by using 2,2-dipyridyl disulfide/PPh (3) in anhydrous dichloromethane in the presence of 1 H -benzotriazole. Mild reaction conditions, short reaction time, easy in handling, wide substrate scope, availability of reagents involved, and moreover avoiding the use of base makes this protocol quite useful for the laboratory practices for N -acylbenzotriazole synthesis.
Recommanded Product: 385-00-2. About 2,6-Difluorobenzoic acid, If you have any questions, you can contact Singh, AS; Agrahari, AK; Mishra, N; Singh, M; Tiwari, VK or concate me.
