ABSTRACT
In the present investigation two amides were synthesized: N, N-diisopropiletanoamida and N, N-dibutyletano-amide, using two different non-conventional sources of activation: microwave and ultrasound. It was shown that the use of microwaves in this type of synthesis greatly increases yields and decreases reaction times. In the synthesis of N, N-diisopropyletanoamide yields were about 75% for the synthesis assisted by microwaves (SAM) and 35% in the ultrasound-assisted synthesis (SAUS). The yields for the N, N-dibutiletanoamida were 73% (SAM) and 45% (SAUS). The reaction times employed were 15 min. (SAM) and 7 hours (SAUS). It is noteworthy that all reactions were carried out in a single step and in the absence of solvent.
