Amination of furfural (FUR) with formamide (AM). Time course for reactants heated by a microwave and b oil bath modeled with the assumption of pseudo-first-order reaction kinetics (black diamond, FUR; gray triangle, FDFAM; red circle, 1; blue triangle, 2; brown triangle, Other products). Rate constants of c microwave (\(\mathop {k}\nolimits_{{i}}^{{\mathrm{mw}}}\)) and oil heating (\(\mathop {k}\nolimits_{{i}}^{{\mathrm{oil}}}\)) and ratios (\(\mathop {k}\nolimits_{{i}}^{{\mathrm{mw}}}\)/\(\mathop {k}\nolimits_{{i}}^{{\mathrm{oil}}}\)) for cascade reactions (i) at reaction conditions (2 mmol FUR, 6 mmol FA, 10 mmol AM, 180 °C). Product distributions for d furfural/formic acid/formamide molar ratios with FUR set at reaction conditions (2 mmol FUR, 200 °C, 3 min). Error bars with standard deviation (σ) of ≤4.3%
