The main purpose is to analyze the characteristics of peculiar solar events that could be produced by ultrarelativistic electrons and try to define the new boundary conditions for the primary energy release during impulsive phase. It seems that submillimeter emission in solar flares is not a rare phenomenon, there is not much evidence, due to the lack of observations in this range of the spectrum. During May 1984 the Sun was observed at 90 GHz with high time resolution and high sensitivity, and evidence was obtained. The May 21, 1984 event, at 1326 UT is the best example of the high energy manifestation during the spectrum and gave us new boundary conditions for the physical phenomena in the Sun. The May 21 event required a detailed analysis of the current interpretation models and suggested the presence of relativistic electrons during the impulsive phase. In this case Syncrotron/inverse compton mechanism was suggested to explain submillimeter/x ray emission and short pulse duration. The new boundary conditions for primary energy release favored Tajima and Sakai's model, based in magnetic island coalescence theory.
