Abstract
Correction for ‘Protection of COOH and OH groups in acid, base and salt free reactions’ by Xiaotao Zhu et al., Green Chem., 2018, 20, 1444–1447.
The authors regret an error in Table 3 on page 1446 of the original article, whereby the structure of compound 6q was wrongly displayed.
The corrected structure is shown below (Fig. 1):
