x), bis (isoindolinone) ethanes (4 a–d) and 3‐hydroxy‐isoindolinones (6 a–h) derivatives is
portrayed from easily accessible starting materials such as 2‐cyanobenzaldehydes (1 a–h)
and different aryl/heteroaryl methyl ketones (2 a–k). The structure of Z‐isomer of 3‐
methylene‐isoindolinone 3 x was confirmed by single crystal X‐ray analysis. The reaction
mechanism studies by control experiments and using O18‐labelled water revealed that the …
