Yield: 95%

Reaction Conditions:

Stage #1:para-dinitrobenzene with iron(III) acetylacetonate;1,1,3,3-Tetramethyldisiloxane in tetrahydrofuran at 60; for 48 h;Inert atmosphere;Sealed tube;
Stage #2: with hydrogenchloride in tetrahydrofuran;diethyl ether for 0.0833333 h;

Steps:

4.1. General
General procedure: In a solution of nitro compound (2 mmol) in 0.6 mL of THF were added Fe(acac)₃ (10 mmol %, 70 mg) and TMDS (1.5 equiv or three Si-H, 0.53 mL). After 24 h (unless otherwise indicated) under heating the reaction mixture was diluted in a minimum of Et₂O with a constant stirring. HCl (2 equiv) in Et₂O was then added dropwise. A precipitate appears; the mixture was stirred for 5 min and filtered. It was washed several times with Et₂O and dried to afford the desired product as a hydrochloride salt.
