Experi-mental results are described in this paper which show that thisanalogy between the triphenyl carbinols and the xanthenolsextends to the derivatives of phenyl acridol (V),. and even to the salts of pyridine and quinoline. The phenylacridols form chloride hydrochlorides VI just asdo the xanthenols and the methoxytriphenylcarbinols. Fromthese hydrochlorides normal chlorides have been prepared, whichin contrast to the colorless benzoid, normal chlorides of the xan-thenols and triphenylcarbinols are quinoid, colored colored acridol chlorides, react however with metallicsilver just as does triphenylchlormethane, forming a metal halideand an unsaturated compound analagous to unsaturated compound is readily oxidizable at the time ofits formation and absorbs an amount of oxygen correspondingexactly to the formation of a peroxide of the type of triphenyl-methylperoxide. Exactly the same type of reaction takes placebetween the metals and the salts of pyridine and quinoline butdoes not take place with open chain ammonium salts. It hasalso been shown that silver halides form double salts with thesalts of the acridols, pyridine an
