This is completely out of the blue, but is there any such chemical that when a person inhales it, they are forced to sleep?

There are a number of inhalation anesthetics, if that's what you mean by sleep, such as halothane and isofluorane (I don't know the chemical structures of these). Of course we've all heard of using ether for such purposes before somewhat safer anesthetics were developed.

But if you didn't mean unconsciousness but just sleep, I don't know of anything.

"Chloroform (real chemical name trichloromethane) is often used on TV by nefarious characters who want to put people to sleep. Usually they pour it onto a rag and then hold it against the victim's nose so they smell it and eventually pass out. Doctors also used to use it as an anesthetic in the olden days to put people to sleep for surgery. It is no longer used for several reasons: 1) it's toxic to the lungs and very irritating to the skin and respiratory tract lining 2) it's carcinogenic 3) we've got a lot better anesthetic agents now that are not so irritating and not carcinogenic."
