Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen. 497-25-6, C3H5NO2.

Copper(I)-catalyzed highly regio- and stereoselective boron addition-protonolysis of alkynamides to give alkenamides
Copper-catalyzed and highly chemoselective reduction of N-alkynylamides by a boron addition-protonolysis protocol is presented. The reaction proceeds with the addition of boryl-copper complex to N-alkynylamides with high regioselectivity and stereoselectivity, followed by regiocontrolled transmetallation of the alpha-site of the alkenylboronate with MeOCuL to afford N-alkenylamides in good yields. Deuterium labeling experiments indicated that both of the alkenyl hydrogen atoms originate from the additive methanol.
