I would not have cc'ed my friend on the "no, I don't want that job" email. It detracts from the main focus. I typically do introductions two ways:
- To: A, B. Body: A, meet B, who is a [great person with such and such skills and experience.] B, meet A, who [is looking for a whatever.] I wanted you two to meet because [as many sentences as you like.]
- To: A. Body: I think you should know about B. Links to website, public resume, twitter handle, blog, careers.SE profile, etc etc. B would be a great fit for the opportunity we discussed today. [Sentence or two about things you know personally about B.]
The first lets the two of them do all the exchanging of information directly. The second provides what you know. It's forwardable - the recruiter can send it straight to someone else without having a bunch of "junk" at the beginning about how you don't want the job, or a long email trail afterwards of the other messages you exchanged.
Don't mix and match. If B is cc'ed, don't provide all that contact stuff, leave it for B to do. Don't write a long bio of B either - a smart B hits reply all and say "Thanks, Evorlor, and great to meet you A," then launches into a paragraph or two about themselves.
So in your case, the decline email should be all about the declining. You can mention in passing you know someone who would be a better fit. Then send a separate email, with a different subject line, using one of the two formats above. Then step away and see what happens.
