In the article “PMA-SiO2–Mediated MCR in PEG-400:
A Greener
Aza-Friedel–Crafts Reaction Leading to 3-Arylmethyl=Diarylmethyl Indoles,”
which was published in Synthetic Communications, Volume 45, Number 4, 2015,
pp. 513–523, the final version of the article was printed with some errors.
• On p. 513 in the Graphical Abstract, the reaction temperature should be corrected
to “90–95 °C” instead of “110–115 °C.”
• On p. 515, in Scheme 1, the reaction temperature should be corrected to “90–95 °C”
instead of “110–115 °C.”
• On p. 515, in line 4 of the Results and Discussion, the sentence reading “ … absence
of any catalyst in PEG-400 at 120 °C … ” should be corrected to “ … absence of
any catalyst in PEG-400 at 90–95 °C … ”
• On p. 517, Table 2, was printed with errors. The corrected version of Table 2 is
presented here:
