Attempted heterocyclization of 5-bromo-2,4-diamino-6-substituted pyrimidines in a mixture of DMF and trialkylamines (Et3N or N,N-diisopropylethylamine) under mild conditions, led to the formation of new dehalogenated ...

the Electron Transfer process

(Thermal Electron Transfer); leading to a single electron transfer from Et3N-DMF complex to

the 5-bromopyrimidine. At least 10 several derivatives of 5-halogenopyrimidines and uracil were

successfully reduced...
