A Festival of Chemistry Entertainments

This publication, part of the yank Chemical Society's Symposium sequence, is a suite of a few pleasant bits of caprice and humor, either intentional and unintended, from the realm of chemistry. beneath these well-known white lab coats essentially beat hearts which are able to find and having fun with the lighter facet in their technological know-how.

3-Triazines 27 it is shown that 1,2,4-triazines bearing mercapto groups exist in the enolic form although their oxygen analogs may apparently exist, or, at least, react as the keto tautomers. , thiourea. Reissert and Grube prepared S-acyl derivatives of 4-mercapto-l,2,3-benzotriazine by treating it with benzoyl chloride and sodium hydroxide or with acetic anhydride and sodium acetate. When treated with sodium and methyl iodide, 4mercapto-l,2,3-benzotriazineforms the S-methyl derivative. Alkaline permanganate converts 4-mercapto-l,2,3-benzotriazineto benzazimide, S being replaced by 0.

It was prepared by Sachs and SteineF by the reaction of nitrous acid with 2-0-aminophenylperimidine (eq. 75). Compound LVI has no melting point but explodes suddenly at 140'. It is soluble in the usual organic solvents and in hot dilute sulfuric acid. In concentrated sulfuric acid it gives a green color, on standing in dilute sulfuric acid, a blue-violet color and, in dilute hydrochloric acid, a blue color. at 50-60'. It is also stable towards alkali. The original name given this compound is o-aminopheny&erimidine azoimide.
