How to get phenylacetate & p-nitrobenzaldehyde from benzene?

Answer 1

Try looking in a good organic chemistry text book. Or, google "p-nitrobenzaldehyde benzene synthesis" and "phenylacetate benzene synthesis" and see what you come up with.

PHENYL-ACETATE
I sent you purposal of industrial and lab's synthesis.
Foundamentally, you should lead acetylation's process of phenol.
How can you obtain phenol by starting from benzene?

In industry, benzene are added iso-propyl's chloride (e.g. one among the "Friedel-Crafts's alkylation") and the catalyst as aluminium's chloride. You get "cumene" or iso-propyl-benzene.
The DOW Chemical Company claimed its patent of "cumene's oxidation", now you get phenol among all products.

In lab's practice, you start by nitration of benzene. The latter is mixed with concentrated nitro-sulphuric acids ; intense warming permit reaction's proceeding. The product is nitro-benzene. The latter receives metal active's powder and in aqueous medium it begins "Beschamps-Brinnemeyer's reaction". By means of alkaline showers, you can retrieve aniline or "ammino-benzene". Aniline is mixed with nitrite's salt and dissoluted them in acidic aqueous solutions ; this is "Griess's procedure" toward "diazo-benzene's salts". The latter salts are separated, hence added in warm and sulphuric acid's solutions. Now, you get phenol among all products.

When isolated (cold surround solidify it), phenol undergoes acylating addiction of acetic anhydride, where HF operates as catalyst. The latter reaction led in warm conditions even.

p-NITRO-BENZALDEHYDE
I sent you purposal of industrial and lab's synthesis.
In industry, benzene are added methyl's chloride (e.g. one among the "Friedel-Crafts's alkylation") and the catalyst as aluminium's chloride. You get "toluene", or methyl-benzene, among all products.
Toluene isolated is placed in nitro-sulphuric acidic mixture and reaction begins by means of very strong conditions, e.g. very high acid concentrations and high temperature. You get "p-nitro-toluene", or p-nitro-methyl-benzene, among all products.
After product's isolation, p-nitro-toluene went warmed to evaporate, thus it undergoes chlorination (gas phase's mixing with chlorine) by means of U.V. irradiation. Among the liquid retrieved by vapour-condensation it is present your intermediate, e.g. p-nitro-benzal-chloride. When it went hydrolized in alkaline aqueous solutions, finally you get p-nitro-benzaldehyde.
As you understood, at this point, your yields become low.

I hope this helps you.

Answer 3

benzene + CUCL+ +HOH+NAOH ----PHENOL
Phenol + CH3COOH ----PHENYL ACETATE.

BENZENE + CrO2Cl2(chromyl chloride) mild oxidation gives benzaldehyde + CON H2SO4+ con HNO3 ----Para-NO2-benzaldehyde
