Calculate Digit Verification of CAS Registry Number 1269431-24:
(9*1)+(8*2)+(7*6)+(6*9)+(5*4)+(4*3)+(3*1)+(2*2)+(1*4)=164
164 % 10 = 4
So 1269431-24-4 is a valid CAS Registry Number.

Transformation of aromatic bromides into aromatic nitriles with n-BuLi, pivalonitrile, and iodine under metal cyanide-free conditions

Uchida, Ko,Togo, Hideo

, (2019)

Various aromatic nitriles could be obtained in good yields by the treatment of aryl bromides with n-butyllithium and then pivalonitrile, followed by the treatment with molecular iodine at 70 °C, without metal cyanides under transition-metal-free conditions. The present reaction proceeds through the radical β-elimination of imino-nitrogen-centered radicals formed from the reactions of imines and N-iodoimines under warming conditions.
