OME前段时间2我发表了一种制备四苯基甲烷的方法。产量相当小，我不得不研究大约 0.5 克烃的溶解度、组成、分子量和硝基衍生物。这种化合物的立体化学兴趣促使我再次研究这个课题，希望获得更高的产量。因此，我回顾了其他人尝试过的大多数制备四苯甲烷的方法。我的结果虽然与其他人发表的结果在细节上有所不同，但大体上是一致的——碳氢化合物不能通过通常的反应获得。我提出的关于四苯基甲烷构成的主要证据之一是，它提供了一种四硝基衍生物，该衍生物与酒精钾不产生有色盐，而大多数较少苯化的甲烷确实对这一测试做出了反应。来证明是否
OME time ago2 I published a method of preparing tetra-phenylmethane. The yield was rather small and I was obliged to study the solubilities, composition, molecular weight, and the nitro derivative on about 0.5 gram of the hydrocarbon. The stereochemical interest attached to this compound has induced me to take up the subject once more, in the hope of obtaining larger yields. I have, therefore, gone over most of the methods which have been tried by others for the preparation of tetraphenylmethane. My results, while differing in detail from those publishedby others, agree in the main,—the hydrocarbon could not be obtained by the usual reactions. One of the main proofs advanced by me for the constitution of tetraphenyl-methane was that it furnished a tetranitro derivative which gave no colored salts with alcoholic potash, while most of the less phenylated methanes do respond to this test. To prove whether
