Corrigendum: Microwave-assisted Knoevenagel-Doebner reaction: An efficient method for naturally occurring phenolic acids synthesis [Front. Chem, 6 (2018) (426)] doi: 10.3389/fchem.2018.00426

Abstract

In the original article, there was a mistake in Table 2. Optimization of the microwave-assisted Knoevenagel-Doebner condensation on vanillin at 50 W. as published. The values in the Eq. of base column for lines 2 to 8 are not accurate. The corrected Table 2. Optimization of the microwave-assisted Knoevenagel-Doebner condensation on vanillin at 50 W. appears below. The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
