You have two things to be addressed over here.

1. Why does your first code does not works ?

Refer the find manual, it has the answer for your question as

Code:
-exec command {} +
.............Only one instance of '{}' is allowed within the command .....

Note: In your first code, you have used the {} two times. ( one in mv, and another in tr which is wrong ).

2. 2>/dev/null
Redirecting errors is not a good practice.

Actually you should understand the error and try to solve it. Your code is trying to rename the files which has no space in it. But your intension is to rename only the files which has space in its name. So you should try to find only the files which has spaces in it, and rename it.
My suggestion is find the file using the following, which will show only the file names which has the space in it.

Code:
find . -name "* *" -type f

There might be better solutions for finding files with spaces in it is names. If some thing is there, let us know.
