Title | Paper, 'Contributions towards the solution of the chemical constitution of isatin [tribulin]' by H [Hermann] Kolbe |
Date | 1885 |
Description | Kolbe writes: 'Notwithstanding that so many facts have been collected with the object of definitely settling the constitution of yet arguments of weight sufficient to support a hypothesis of its rational constitution, or indeed to raise it above the mere level of a hypoteare still wanting. The property of isatin of forming crystalline compounds with the alkaline bisulphites led to the supposition of its belonging to the class of aldehydes or ketones ; its property, when in contact with bases, of assimilating the elements of water, and therewith forming isatic acid, from which stronger acids regenerate isatin, placed it in analogy with oxindol or cumarin, &c., which show a similar behaviour.'
