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):

Fig. 1 Structure of compound 6q.

This correction is supported by X-ray analysis of the crystal of compound 6q. The crystal data and structure refinement for 6q are shown in Table 1 below. All of the data match the compound (named α-glucose pentaacetate) published in Acta Crystallographica1 with the CCDC number 1320240.
