Heterocyclic organoboron compounds. Part II. Some 2-aryl-benzo- and -naphtho-1,3,2-di-azaborolines and -oxaborolens

Ultraviolet spectrometry

“…Some organometallics include ethyl aryl (bromomercuri) acetates (28), spiroborates (27), triarylboranes (508), phenvlchlorostannanes and phenylchlorogermanes (420), and heterocyclic boron compounds (275). The ultraviolet spectra of Ar-organosilyl ketimines (117), substituted 1,2-diphenvltetramethyldisilane (529) and cyclic silicon compounds (255) were also studied.…”
