Abstract

Correction for ‘Green synthesis of 1,4-benzodiazepines over La₂O₃ and La(OH)₃ catalysts: possibility of Langmuir–Hinshelwood adsorption’ by Archana Singh et al., RSC Adv., 2016, 6, 103455–103462.

The authors regret that in the original manuscript there were some errors in the structures displayed in Scheme 1 and Table 1. The correct scheme and table are presented herein.


	Scheme 1 Schematic of a synthetic strategy for preparation of 1,4-benzodiazepine derivatives.

Table 1 List of the reactions performed with the different aldehydes, their reaction times and the isolated product yield
