The Synthesis and Properties of 2,2‐Diphenylindoxyl

The synthesis of the unknown 2,2-diphenylindoxyl (Ia) following the path VI VII VIII Ia it herein described. The chemical evidence, and the infrared and ultraviolet spectra are in consonance with the structural formula. The unresolved signal at 5.24 p.p.m., appearing in the NMR spectrum of Ia is assigned to the N - H proton.
