Sonication of aryl halides, t-butyl isocyanate and sodium in THF leads to an organosodium intermediate which is easily and regioselectively ortho-lithiated and reacted with electrophilic reagents.

This paper presents a dualistic behavior of 2‐substituted‐3‐hydroxyisoindolones in reactions with sec‐butyllithium (sec‐BuLi). 2‐tert‐Butyl‐3‐hydroxy‐2,3‐dihydro‐1H‐isoindol‐1‐one (1a) treated with sec‐BuLi undergoes metalation at position 7. On the other hand, the reaction between 3‐hydroxy‐2‐phenyl‐2,3‐dihydroxyisoindol‐1‐one (1j) and sec‐BuLi results in 3‐sec‐butyl‐2‐phenyl‐2,3‐dihydroisiondol‐1‐one
