Here is a possible route for the preparation of nitrobenzene starting from acetylene:

1. Acetylene can be converted to benzene through cyclotrimerization. This reaction is typically catalyzed by a transition metal catalyst, such as nickel.

2. Once you have benzene, you can then nitrate it to form nitrobenzene. This is typically done by treating the benzene with a mixture of concentrated nitric and sulfuric acids.

Here are the reactions:

1. 3HC≡CH → C6H6 (in the presence of Ni catalyst)

2. C6H6 + HNO3 → C6H5NO2 + H2O (in the presence of H2SO4)

Please note that these reactions should be carried out under controlled conditions in a laboratory by a trained professional, as they can be dangerous.
