THE REACTIONS OF BENZENEDIAZONIUM IONS WITH SOME PURINES AND PYRIMIDINES
Hung, Ming-Hong,Stock, Leon M.
, p. 67 - 75 (2007/10/02)
The reactions of certain pyrimidines and purines with benzenediazonium ions in basic solution have been investigated to determine whether the reactions provide triazenes, azo coupling, or phenylation products.Under these conditions, the anion of uracil fo
