The relative reactivity of heteroatomic compounds (PhM; M = SeR, SnR3, TeR, I) towards BuLi was estimated by competitive experiments. The rates of exchange reactions in THF increase in the order I > Te >> Sn >> Se with a ratio of 1000:300:15: 1 at -70 "C when R =Bu. Me,SnPh underwent exchange much f
The effect of substituents on pi radical reactions of para-substituted tetraphenylporphyrins was investigated by cyclic voltammetry in methylene chloride. In all cases electron donating substituents produced a more difficult reduction and an easier oxidation. Plots of E1/2 vs. a yielded Hammett line
## Abstract Rate data are reported for the reactions of a series of Xβphenyl 2,4,6βtrinitrophenyl ethers 1aβe[X = H, 4βNO~2~, 2βNO~2~, 2,4β(NO~2~)~2~, or 2,6β(NO~2~)~2~] with substituted anilines 2aβe [Y = H, 2βCH~3~, 2,4β(CH~3~)~2~, 2,6β(CH~3~)~2~, or NβCH~3~] in acetonitrile as solvent. For indiv
