N-methylpyrrole
WebJan 23, 2024 · Nitrogen is more electronegative than hydrogen and so attracts the bonding electrons in the ammonia molecule towards itself. That means that in addition to the lone pair, there is a build-up of negative charge around the nitrogen atom. That combination of extra negativity and active lone pair attracts the new hydrogen from the water. WebDec 28, 2024 · Notably, when the pyrrole and N-methylpyrrole were employed, a comparable yield was obtained. To test the feasibility of potential large-scale application of the process, the reaction of 3-(trifluoroacetyl)coumarin 1a with 2-methylpyrrole 2a was carried out at the 10 mmol scale under the standard conditions ( Scheme 1 ).
