[R] Problem with the str_replace function

[phii m@iii@g oii phiiipsmith@c@]

I have a problem with the str_replace() function in the stringr package. 
Please refer to my reprex below.

I start with a vector of strings, called x. Some of the strings contain 
apostrophes and brackets. I make a simple replacement as with x1, and 
there is no problem. I make another simple replacement, x2, where the 
pattern string has an apostrophe. Again no problem. Then I make a third 
replacement, x3, where the pattern has opening and closing brackets and 
the function still works fine. Finally I make a replacement where the 
pattern has both an apostrophe and opening and closing brackets and the 
replacement does not work. I tried to solve this by putting backslashes 
before the apostrophe and/or the brackets, but that accomplished 
nothing. I am stumped.
