In connection with the interesting problem of the possible existence of derivatives of symtri-t- butylbenzene with two or three functional groups, the nitration of some derivatives of 1, 3, 5- tri-t-butylbenzene has been undertaken. Sym-tri-methyl-, or tri-isopropy lbenzenes bearing three functional groups, 1) and sym-trit-butylbenzenes with one functional group2) have already been known, but derivatives of the latter hydrocarbon bearing two or three ...
