An elimination-addition mechanism, probably involving a "benzyne" intermediate, has been established for the rearrangements which often occur in the conversion of non-activated aryl halides to arylamines with metallic amides. The evidence for the "be

The respective orientations of amine and substituent groups resulting from aminations of a number of substituted halobenzenes have been determined qualitatively and correlated with the aid of a previously postulated elimination-addition (“benzyne

Investigation of the extent of isotope-position rearrangement in carbonium ion-type reactions of ^(14)C-labeled cyclopropylcarbinyl derivatives has revealed that the three methylene groups of the starting material achieve a striking degree of equival

It has been shown by the ^(14)C-tracer technique that cyclobutanone is formed from the reaction OF ketene with diszomethane-^(14)C via an intermediate possessing the symmetry properties of cyclopropanone.

Base strength measurements with substituted anilines indicate direct conjugation between the amino groups and electron-attracting unsaturated substituent groups such as —NO_2,—C≡N, etc. (I). Such conjugation delocalizes the unshared electron pa

The dipole moment (3.12 D) found for bis-(p-chlorophenylcyclopentadienyl)-iron indicates a molecular configuration having the p-chlorophenyl groups in rather close proximity to one another.

In recent years, isotopes have become one of the most potent tools available to the organic chemist for determination of reaction mechanisms, quantitative analysis, and elucidation of structures. The purpose of this review is to illustrate a variety
