When boron trifluoride (\(\mathrm{BF_3}\)) reacts with lithium aluminium hydride (\(\mathrm{LiAlH_4}\)) 
in dry ether at low temperature, a gaseous compound \( \mathrm{A} \) is formed. 

Compound \( \mathrm{A} \) is then treated with perhaloalkyl nitrile (\(\mathrm{CCl_3CN}\)) in the presence 
of dry DME solvent at \( 85~^\circ\mathrm{C} \) for 15~h under nitrogen atmosphere, to form compound \( \mathrm{B} \).

Then compound \( \mathrm{B} \) on further heating at 
\( 140~^\circ\mathrm{C} \) for 2~h in dry mineral spirit and undergoes cyclization 
to yield compound \( \mathrm{C} \).
Then find out the IUPAC name of compound C?

Grading rubric:
criterion: Explicitly states the balanced stoichiometric relationship between BF_3 and LiAlH_4 leading to formation of B_2H_6, including coefficients.
weight: 10
criterion: Explicitly assigns compound B the chemical formula BH_2NHCH_2CCl_3.
weight: 20
criterion: Explicitly states that compound B contains exactly two B–H bonds per molecule.
weight: 10
criterion: Explicitly states that each molecule of compound B contributes exactly one boron atom to the cyclic framework of compound C.
weight: 10
criterion: Explicitly states that the cyclization step releases three equivalents of H_2.
weight: 20
criterion: Explicitly identifies compound C as a neutral borazine derivative formed via dehydrogenative cyclotrimerization of aminoborane units rather than nitrile trimerization.
weight: 10
criterion: Explicitly names the final product as 1,3,5-tris[(trichloromethyl)methyl]borazine.
weight: 20

Answer:
1,3,5-tris[(trichloromethyl)methyl]borazine
