Updegraff, D. M. published the artcileTriarylborane complexes, a new series of broad-spectrum germicides, Application of Triphenyl(pyridin-1-ium-1-yl)borate, the publication is Journal of Infectious Diseases (1964), 304-10, database is CAplus.
More than 100 coordination complexes of triarylboranes with amines and substituted phosphines were screened against bacteria and fungi, and selected members were also screened against protozoa. The chem. stable complexes of triphenylborane and tris(para-substituted phenyl)borane were powerful broad-spectrum germicides, fungicides, and protozoicides.
Journal of Infectious Diseases published new progress about 971-66-4. 971-66-4 belongs to pyridine-derivatives, auxiliary class Pyridine,Benzene, name is Triphenyl(pyridin-1-ium-1-yl)borate, and the molecular formula is C19H22BNO5, Application of Triphenyl(pyridin-1-ium-1-yl)borate.
