✦ Synopsis
The indium-catalysed coupling of propargyl bromide with a variety of imines and imine oxides afforded the corresponding propargylated products in high yields under mild conditions.

Allylindium adds to a variety of tosyl and aryl hydrazones derived from aromatic aldehydes and ketones at ambient temperature in a DMF-H 2 O solvent system to afford homoallylic tosyl hydrazides and homoallylic hydrazines, respectively.

Several aromatic and aliphatic amine-N-oxides were deoxygenated to the corresponding amines in good to quantitative yield using indium metal in neutral aqueous media. Other functional groups such as alkenes, halides, esters, ethers, nitriles, amides and sulfones are unaffected under the present reac
