Yellow coloration develops in polystyrene under 2537 A. radiation a t comparable rates whether or not oxygen is present. Thus the commonly accepted view that coloration is a manifestation of oxidation is wrong. The coloration increases in intensity with time but does not move toward the red end of t

We have now been able to show that a nucleophilic addition takes place on reaction of triphenylstannyllithium with carbon disulfide. The initial product (1) can be trapped by alkylation with methyl or ethyl iodide in tetrahydrofuran (THE'). ## 20 "c After separation by column chromatography, the p
