Reduction of indolin-2-ones with lithium aluminium hydride (LAH) or diisobutylaluminum hydride (DIBAL) and desulfurization of indoline-2-thiones with Raney-Ni were investigated. Treatment of indoline-2-ones 1 with LAH or DIBAL yield indoles 4 and/or indolines 3 in moderate-to high yield depending on the substituents at N and C(3) of 1. Indoline-2-thiones 2 were desulfurized with Raney-Ni to give indoles

Tantalizingly simple: The common organometallic starting material TaMe3Cl2 can be used for the catalytic CH functionalization reaction, hydroaminoalkylation. The substrate scope for this readily accessed compound includes unactivated terminal and internal alkenes, styrene derivatives, and both alkylaryl‐ and dialkyl secondary amines (see scheme).
