Abstract
THIS series has attained a recognised position as a useful adjunct to research workers and others who are engaged in the practice of organic chemistry. The latest issue contains precise directions, which have been independently checked in each instance, for carrying out thirty organic preparations. Although the contributors to this volume are mainly American, the international character of the undertaking is indicated by the fact that the list of authors includes the names of Holleman (Amsterdam), Lapworth (Manchester), Reverdin (Geneva), and Ziegler (Marburg). Among interesting substances the preparation of which is described are chloro-acetamide, p-chloromercuribenzoic acid, diphenic acid, furan, furfuralacetone, guanidine nitrate, nitroguanidine, a-methyl mannoside, pentene-2, tri-phenyl stibine, xanthone, and anhydrous hydrogen cyanide. In the last-named preparation mention is made of Gattermann's interesting recommendation “that the operator smoke during the preparation, for he found that a trace of hydrogen cyanide is sufficient to give the tobacco smoke a highly characteristic flavour. This preliminary warning is useful in case of leaky apparatus or a faulty hood.” Most of the methods given are based on known reactions, but considerable alterations in the published conditions have often been found necessary in order to secure satisfactory yields. In the case of anhydro-2-hydroxymercuri-3-nitro-benzoic acid, here described by Whitmore, Culhane, and Neher, no method of preparation has hitherto appeared in the literature.
