Abstract

Correction for 'A novel, facile, rapid, solvent free protocol for the one pot green synthesis of chromeno[2,3-d]pyrimidines using reusable nano ZnAl2O4 – a NOSE approach and photophysical studies' by Balijapalli Umamahesh et al., RSC Adv., 2015, 5, 6578–6587.

The molecular formulae for compounds 4a–r in the Experimental section have been inadvertently given as C27H21N for all the molecules. The correct formulae are given below. All the other data are correct.

Corrected molecular formulae:

4a: C21H19N3O3

4b: C29H23N3O3

4c: C23H23N3O5

4d: C25H27N3O5

4e: C21H17Br2N3O3

4f: C22H19N5O6

4g: C22H21N3O2

4h: C24H25N3O4

4i: C26H29N3O4

4j: C22H19Br2N3O2

4k: C27H24N4O2

4l: C28H26N4O2

4m: C34H30N4O2

4n: C21H19N3O2

4o: C23H23N3O4

4p: C25H27N3O4

4q: C23H25N3O4

4r: C21H19Br2N3O2
