The reduction of a dinitro ketone to an azo ketone is best achieved with glucose. 2,2 -Dinitrobenzophenone treated with glucose in methanolic sodium hydroxide at 60° afforded 82% of dibenzo[c,f [i 2]diazepin-l 1-one whereas lithium aluminum hydride yielded 24% of bis(o-nitrophenyl)methanol [575], Conversion of aromatic nitro ketones with a nitro group in the ring into amino ketones has been achieved by means of stannous chloride, which reduced 4-chloro-3-nitroacetophenone to 3-amino-4-chloroacetophenone in 91% yield [178]. A more dependable reagent for this purpose proved to be iron which, in acidic medium, reduced m-nitroacetophenone to m-aminoacetophenone in 80% yield and o-nitrobenzophenone to o-aminobenzophenone in 89% yield (stannous chloride was unsuccessful in the latter case) [903]. Iron has also been used for the reduction of o-nitrochalcone, 3-(o-nitrophenyl)-l-phenyl-2-propen-l-one, to 3-(o-aminophenyl)-l-phenyl-2-propen-l-one in 80% yield [555]. 

Acylmetallocenes undergo many reactions shown by acylbenzenes (35, 87, 91, 116, 124), but a detailed discussion is not presented here. Reductions with either lithium aluminum hydride or sodium borohydride give the corresponding carbinols, while Clemmensen reduction, reduction with lithium aluminum hydride plus aluminum chloride, catalytic hydrogenation, etc., yield corresponding alkyl derivatives. Acetylferrocenes undergo a variety of base condensation reactions and can be oxidized to ferrocenecarboxylic acids without apparent oxidation of the iron atom. 

Thus they treated the cisltrans mixture obtained by isomerization with iron pentacarbonyl and after decomposition of the complex with ferric chloride obtained the desired all-trans-tetraene ester (4) in 51% yield. The remaining steps in the synthesis involved lithium aluminum hydride reduction (80% yield) and Mn02 oxidation (52% yield). 

Attempts to convert the sulfones back into PASHs have been successful with a number of agents such as various metals (zinc, tin, magnesium, aluminum, iron, and nickel) in acetic acid, palladium on carbon with hydrazine, stannous chloride, lithium triethylborohydride, diphenylsi-lane, sodium borohydride, boron trifluoride, dicyclohexylcarbodiimide, triethyl phosphite, dimethyl dichlorosUane with lithium aluminum hydride, diphenylsilane, and triphenyl phosphine with iodine. However, none of them cleanly effect this conversion.
