Para-Nitrobenzoyl chloride

Some data for the reaction between para nitrobenzoyl chloride (A) and n-butanol (B) were obtained at two starting concentrations with stoichiometric proportions [Ashdown, JACS 52 268, 1930). The reaction is A + 2B Products... 

A double metal oxide sulfate solid supwacid, namely, alumina-zirconia/persulfate, can be prepared by treatment of a mixture of aluminum hydroxide and zirconium(IV) hydroxide with an aqueous solution of ammonium persulfate, followed by calcination at 650°C [85]. This catalyst can be utilized in the benzoylation of arenes with benzoyl and para-nitrobenzoyl chloride giving benzophenones in 60-89% yield. Even if 1 g of catalyst is needed for 40mmol of acyl chloride, the process seems to be quite useful because the catalyst can be readily regenerated by heating after washing with acetone and diethyl ether and reused four times. 

Para-Nitrobenzoate. A solid, mp 106-8° prepd the same as above using p-nitrobenzoyl chloride, yield 60%. Urbanski states that this compd has great expl strength and low sens to shock (Ref 4)... 

The average yields were 50 to 80 per cent, in the case of m-aniino derivatives, and 30 to 50 per cent, in the case of o- and p-eompounds. These structures were later modified by replacing the nitrobenzoyl chlorides by para-substituted wi-nitrobenzoyl chlorides, in which the group 11 in the paro-positionwas one of the following CII3, OCII3, O.COj.CjHs...
