The photolysis of aryl iodides in the presence of boron halides results in the formation of arylboron dihalides and diarylboron halides by free-radical substitution reactions. Hydrolysis of the products gives the corresponding boronic and borinic acids. Alkyl iodides and di-iodo-compounds behave in a similar manner. The photolysis and subsequent hydrolysis of mixtures of bromo- or chloro-benzene with

The kinetics of the autoxidation of a series of n-, s-, and t-butylboron compounds in iso-octane at 30° have been investigated. The reactions of tri-n- and tri-s-butylboranes (and of triphenylborane) were normally controlled by the rate of diffusion of oxygen into the solution but proceeded at measurable rates in the presence of pyridine which reduced the concentration of the boranes by complexation

Trialkylboroxines in solution react with oxygen to give organoperoxyboron compounds. Tri-t-butylboroxine gives tri-t-butylperoxyboroxine in good yield. With tri-s-butylboroxine the reaction proceeds to about 80% completion, and with tri-n-butylboroxine a maximum of only about two thirds of the theoretical amount of oxygen is absorbed. The mechanism of the oxidation is discussed, and it is pointed out
