All the verbiage on this page boils down to the simple fact that some 3600 miscel­ laneous compounds may be conveniently purchased in laboratory quantities as Eastman Organic Chemicals from Distillation Products Industries (Rochester 3, Ν. Υ.), which will upon request mail a catalog of these wares. Having already ab­ sorbed this much, the reader is assured that (with statistically insignificant excep^ tions) he risks little by a stubborn refusal to be further detained here.

ORGANICS

Isn't it exciting that during the year just past the number of Eastman Organic Chemicals went up from "some 3500" to "some 3600" ! This must mean we are now adding new ones at a faster rate than we are dropping old ones. Accessions, all bright with gleaming new optimism, come about in various ways. For example—

7462 2-Bromo-2-phenylacetophenone 10 g. ..$3.55 Those who know this compound best call it "desyl bromide." Here's why: Benzoin (Eastman 302) is C6HS—C—CH—CeH5

Ο Η Hence, when a bromine replaces one of the hydrogens, viz. C6H6—C—CH—C6H5, it becomes desyl bromide. We could II I Ο Br probably think of more to say about desyl bromide if we had to, but we don't have to.

2,5-Diphenyl-p-dithiin

5g. . .$4.55 We attended a very, very fancy discussion of resonance states in heterocyclic compounds of sulfur. The man was trying to ele­ vate us to a level of chemical understanding where in our mind's ear we would hear the electrons clicking in and out of the dif­ ferent orbital shells of the sulfur atom. We were having a tough time. Our mind has been dulled by immersion in commerce and trade. But we distinctly heard him speak of the dithiadiene ring as starting material for a whole new series of organic com­ pounds, and he practically promised us that 2,5-Diphenyl-pdithiin is easy to make. We took heart and tried it. Another victory. 7443
