Dear Dr. B. B. Ivanova,

Thanks for your reply.  I am new to this chemistry. I am using the following protocol from literature. Let me explain my doubt again.

I am analyzing my synthesized carborane derivatives with a Pd-Stain which is having PdCl2, water and Conc. HCl. I usually spot my compound on TLC glass plate and I run it in suitable solvent. Later, I am immersing the TLC in Pd-stain and drying rapidly in hot air. I can able to see some dark spots in TLC.

So, please explain me what actually happening between my carborane derivative and Pd-stain here?

Only thing I know that some reduction reaction is happening here. But, I do not know the relevant particulars about it. Please explain me.

You should also be aware that Pd salts can catalyze the hydrolysis of carboranes in aqueous solution.
