Osyanin, Vitaly A. published the artcileAlkylation of 5-aryltetrazoles with 2- and 4-hydroxybenzyl alcohols, Formula: C8H5F3N4, the publication is Chemistry of Heterocyclic Compounds (New York, NY, United States) (2015), 51(11-12), 984-990, database is CAplus.
The reaction of salicylic alc. with 5-aryltetrazoles gave mixtures of 2-[(5-aryl-1H-tetrazol-1-yl)methyl]- and 2-[(5-aryl-2H-tetrazol-2-yl)methyl]phenols. In the case of other ortho- and para-hydroxybenzyl alcs., 2,5-disubstituted products were formed selectively. The criteria for detecting 1,5- and 2,5-disubstituted N-benzyltetrazoles by standard 1H and 13C NMR spectroscopy have been identified.
Chemistry of Heterocyclic Compounds (New York, NY, United States) published new progress about 2251-79-8. 2251-79-8 belongs to isoxazole, auxiliary class Trifluoromethyl,Fluoride,Benzene, name is 5-(4-(Trifluoromethyl)phenyl)-1H-tetrazole, and the molecular formula is C8H5F3N4, Formula: C8H5F3N4.
