Calculate Digit Verification of CAS Registry Number 142312-12:
(8*1)+(7*4)+(6*2)+(5*3)+(4*1)+(3*2)+(2*1)+(1*2)=77

Photochemical Arylaminomethylation of the Pyrazine Derivatives Having Electronegative Substituents

Igarashi, Mamoru,Tada, Masaru

, p. 2277 - 2288 (2007/10/02)

5,6-Dichloropyrazine-2,3-dicarbonitrile (1), 2,3-dichloroquinoxaline (2), and pyrazine-2,3-dicarbonitrile (3) were photolyzed in acetonitrile in the presence of N-acyl-N-trimethylsilylmethylanilines (4 or 5).The photolysis is proposed to give an N-acylanilinomethyl radical by an electron transfer followed by the rupture of a trimethylsilyl cation.The anilinomethyl radical thus formed couples with the radical anion from the diazines to give the substitution products (6-9 and 11-14) of 1-3.
