Abstract
Correction for ‘An efficient and rapid intramolecular cyclization of a quadruple Mannich reaction for one-pot synthesis of pentaazaphenalenes and their antimicrobial activities’ by Ahmed F. M. EL-Mahdy et al., RSC Adv., 2016, 6, 92134–92143.
In the original manuscript, in the subsection “5,9-Di(2-naphthyl)-1-thioxo-5,6,9,10-tetrahydro-4H,8H-2,5,7,9,11-pentaazaphenalene-3-one (3k),” incorrect values were given for the elemental analysis of C28H23N5OS. The correct elemental analysis values for this compound are given below.
Anal. calcd for C28H23N5OS (477.58): C, 70.42; H, 4.85; N, 14.66; S, 6.71%; found: C, 70.89; H, 4.58; N, 14.72; S, 7.00%.
