Calculate Digit Verification of CAS Registry Number 1279720-39:
(9*1)+(8*2)+(7*7)+(6*9)+(5*7)+(4*2)+(3*0)+(2*3)+(1*9)=186
186 % 10 = 6

Copper (II) chloride / tetrabutylammonium bromide catalyzed oxidation of 2,6-diisopropylnaphthalene and 4,4′-diisopropylbiphenyl

Orlinska, Beata J.,Zawadiak, Jan M.

experimental part, p. 285 - 290 (2011/12/02)

The oxidation processes of 2,6-diisopropylnaphthalene and 4,4′-diisopropylbiphenyl with oxygen in the presence of a catalyst, composed of copper(II) chloride and tetrabutylammonium bromide, were investigated. It was found that, in essence, only one isopropyl group undergoes oxidation, and obtained mixtures contained mainly peroxide, alcohol, ketone and only small amounts of hydroperoxide.
