111 oonneotion with our work on the determination of the baee rtrengtho of indole derivatives,' It became of lmportanee to study the dlmere whloh some of thee8 oompounde form in acldlo eolutlone. While strtaottare I was deflnltely proved for lndolo dlmer,* no reoent data were available on ekatole direr, althou@ Its rtructure had been 8 oatter of dispute between 0ddo,3 who proposed a pentaoyollo formula, and Sehalt%-DulJlont,4 who favoured Instead the more likely formulation II, but did not give a real proof for It. A rrtruoture mlmilar to that of dllndole (I) was evidently lapoeelble for dlakatole, but III eeemed to be a poeslble alternative for II, on the baela of our remalte on the oomparatire borrloltlee of lndole and Its me-1 derIvatIvea.'
