In LOTR, is the disappearance of the Ent-Wives during or before the War of the Last Alliance connected with the appearance of the Trolls?
Since Orcs were corrupted Elves, did Sauron enslave the Ent-Wives and thus make trolls in an analogous process?

No. Trolls were created by Morgoth prior to the First Age, long before the Entwives disappeared. However, it's likely Ents in general were corrupted to form Trolls, as Morgoth intended them to be a mockery of the Ents.
From wikipedia: Tolkien himself spent much time considering what actually happened to the Entwives (at one point simply saying even he didn't know), but eventually he stated in Letters #144:
I think that in fact the Entwives have disappeared for good, being destroyed with their gardens in the War of the Last Alliance...
I think it is mentioned by Treebeard that the entwives moved east. If they continued moving east we might have to look to the far east of middle earth, an even more mythical place than the middle earth with which we are familiar! Even Gandalf wouldn't go there! Another theory might be that the entwives originally cultivated the beautiful gardens of Ithilien.
Despite the accepted answer above, Tolkien did leave the merest hint as to the possible fate of the Entwives, in a conversation between Sam Gamgee and Ted Sandyman in the first chapter of the Fellowship of the Ring, Sam asks:
But what about these Tree-men, these giants, as you might call them? They do say that one bigger than a tree was seen up away beyond the North Moors not long back ... But this one was as big as an elm tree, and walking – walking seven yards to a stride, if it was an inch.
This is all we have to go on, but it seems an Ent-like creature had been wandering around Eriador, and was seen by one of Sam's relatives in or near the northern borders of the Shire.
